VAIO Laptops were the best. *sigh*. I still miss mine. I had two and then Sony stopped making them.
I think I've been quite good at sweating my assets. My current laptop is from 2014, the previous from 2007, and the one before from 2003. All are still usable, though modern software demands have made the older ones a bit sluggish, and miniaturisation has made them seem less portable than they once were. Your post is probably not a bad reminder to start putting some money aside for a replacement next year.

Also, I didn't realise people actually bought Acorns for home use. Our school had plenty of RiscPCs, and I occasionally saw them in TV playout automation systems, but never heard of much of a consumer push.
My first computer was a ZX 81 as well. Once we’d replaced the Sinclair ram pack (16k!) with a wobble free Memotech design, it was a cracking little machine. Many happy memories.
You’ll be able to get Acorn RISC PCs again from the end of this year, when Apple begins its shift to ARM processors for Macs.
My current Dell laptop is 10 this year, and still gets heavy daily use. Although parts of it are like grandma's broom and quite a bit younger; I tend to wear out the keyboard every few years and I upgraded it to SSDs one Amazon prime day a few years back. I've been thinking about replacing it for several years, on and off, but I have not yet found a suitable replacement at a price I like.
I've got my latest laptop on order, as my previous one is around 12 years old and really is close to dying forever. Currently takes around five minutes from boot up to then login and it to reach a stable enough state to not crash when I try to open something.

Like my previous one, the new one is very much mid-range, but I was amazed to find the spec is only twice as good (speed, memory, hard disk size).

I used to get a new computer every five years or so before that, just to keep pace with technology, with frequent upgrades to keep them useful.

I think the big difference to me is that I now have a smartphone, which by their nature need to be replaced every three years of so. I originally saw them as being a secondary device to the PC, but over time the convenience means it is now my primary. Use the PC for printing out things, writing letters, and being my main photo archive.

Maybe having a fast, light new laptop. Will bring it back into being used a lot more.
Although each one cost the same, you always got more for the price, back in the day stuff like modems, network cards, sound etc. were add-ons, now they come as standard, what you don't see now is the obvious jump in speeds, back in the 486 era, each upgrade was noticeably quicker than the last, now, unless you are doing something big like video or gaming, they are as fast as you need for the majority of tasks, for example look at how the gap between the purchases on your list has started to grow.

As far as technology is concerned, I'm a fan of 'its the second mouse that gets the cheese', let others buy the cutting edge stuff and find the bugs, I'll buy it when it's reliable.

I bought my current laptop for broadband access, I am considering buying another sooner rather than later simply because of its age, I may go Chromebook, or buy that and a Windows one as well, I avoid Apple as I think that they are price gouging scumbags.
Why are laptops so popular? More expensive for same spec, small screens, running hot, fan noise, hard to replace parts, pervious to coffee, tea, water, slowly dying battery...

Desktop for me every day, this one pays the bills and I bought it in 2012.
Regarding the usb sockets situation, I have an expansion unit that gives me 8 usb sockets, and is mains powered to cope but does also seem that downloading photos tends to be faster than plugging directly into the computer.
You bought Computer 7 on my daughter's 10th birthday. I remember just how much she wanted her own computer to be among her pile of presents. She had to wait a few years.
I think my first computer was a NewBrain. Produced by a company called Grundy Business Systems, it was intended to be the original BBC micro. I think they couldn't cope with demand, so Acorn won out. But it was a fabulous computer at the time, especially when expanded with the floppy disc drive!
Where possible I upgrade my existing computers although I did buy 3 new ones when Windows 10 came out.
My most recent upgrade has been to replace the Hard disk in one laptop and one desktop with solid state drives.
Your flat seems to be a Tardis - the sheer amount of stuff that you keep there!
I still have my Vaio laptop, it runs Windows 10 like a charm (although I'm regularly scoffed at for the measly-by-today's-standards storage capacity). As long as you take regular backups, if it ain't broke don't fix it.
It's a bit late now, but if your Dell Dimension's hard drive had gone, it was probably repairable by simply adding a new hard drive. a joy of desktop PCs was that they were incredibly easy to repair or upgrade. As a teenager in the mid 1990s I was always adding bits of ram or extra hard drives to mine. At one time I pretty much built my own new one from scratch. I have a home server which is basically a tiny desktop case, and the other year age started getting to the hardrives. The server has two - mirroring each other. All I had to do was take off the case, whip out one of the hard drives, put the new one in, turn it on and leave it to copy all the files over. Each hard drive replacement took no more than 20 minutes.

Laptops are far harder - I managed to replace a speaker on my partner's elderly HP laptop some years ago after it popped. It was a nightmare, then a few weeks later the new one popped so it's been running for years with a broken left speaker.

My shortest lived PC incidentally was a Lenovo Ideapad. The hinge that opened it up broke a whopping 23 months after me buying it. Thankfully I'd bought it from John Lewis with a 2 year warranty. They did decide it was "beyond economical repair" which was amazing for something so new.
Sinclair also sold the ZX80 as a kit to solder together, which made it a bit cheaper so I went that route.
Worked first-time, hurrah (and phew)!
...but when is the right time to buy a new one?
When I install one on a home network, I always replace the default 'Computer Name' with something less mechanical.
Some of the names I have used: Delia (a Dell machine), Minnie (one in a very small case), Neccy (one with an NEC monitor) and Atom (named after its processor chip).
For Computer 3 if it has a battery inside they are very prone to leaking and unfortunately the resulting acid can completely destroy the motherboard and other components. So if there is a battery I'd look to open it up and remove it to reduce any further damage (though it may already be too late). Also capacitors can fail and leak which is another common problem.

It's quite a rare computer now so worth hanging on to I think but how likely it is to work again would likely depend on if the battery has caused damage.
Most people carry a more powerful device than computers 1-6 and possibly 7 in their pockets now.
When something irreparable fails (not the HD/SSD or memory) and the machine is out of warranty ... then don't buy a new one unless you are a gamer.

I have had excellent results with reconditioned business - not consumer - machines, which can be got from eBay for not much and are usually in good condition (maybe a few marks on the case or the screen, but nothing disastrous) and built like tanks.

I currently use a Thinkpad Carbon X1 which cost £300 - about a sixth of what it originally cost three and a half years ago - and it is a great machine. It was top of the range by some distance at the time, and it shows.
> ...but when is the right time to buy a new one?

Planned - set a limit for how long you keep a device and replace it periodically before it's performance degrades and you can (if you wish) still recover a small amount of money by selling the old unit.

Semi-reactive - When the old computer is disappointing or annoying you more than once per day, begin checking out what's available or due for release soon. Then take your time to get the deal you want before you lose patience with the existing device.

Reactive - either respond to a nice offer randomly emerging on a nice bit of kit, or wait until your current device fails, buy in a rush and hope your backups are good.
When is the right time to buy a new one?

In the old days, this seemed to be driven by new features; with one exception, I bought new machines when the old ones could not do what I wanted them to do. You quoted similar reasons.

Nowadays, while still true, it's to a lesser extent. Also, I increasingly find the removal of features, notably connectors, a strong reason to stick with what you've got: As an ex audio pro, I prefer my optical out. I still use an old pentium for its SCSI connection.

Any new machine without certain features means I'd have to upgrade other hardware too, so the "right time" to buy a new computer is being pushed back more and more, and many of the newly introduced features don't look like must-haves anymore.
You buy a new one if your existing one is beyond economic repair, or a major new operating system / feature comes out which you want and cannot run or add to your old hardware.
I got my first home computer during early 2010, so quite late compared to other people.
Ungraded after Microsoft ceased Vista support as couldn’t risk long outage trying another operating system without backup computer.
Now it runs better than ever on Ubuntu so didn’t need to buy new computer, although it’s reassuring to have two computers.
New computer started on Windows 10, but after a Microsoft forced update crashed it, that too runs Ubuntu.
It’s much easier changing software when you have a backup computer.
As expected when I opened the comments most or all of the commenters are male (or seem to be male as using a male name) (though that's assuming a lot as well). Have you ever done a survey of your readers or commenters DG to find out who reads your blog? Maybe females like me just enjoy reading and rarely comment .

dg writes: Last time I asked, in 2016, the split was 88% male 12% female.
1st machine was a Spectrum plus in '83±. Well used for a couple of years, then I discovered guitars.

I got an Apple Mac LCIII in '93 (still have it in a wardrobe), since when I've not used anything but macs work or home. Followed by a 4400, a G4, an eMac, a 24" iMac, a 27" iMac and in 2018 another 27" iMac. So thats 1 roughly every 4 years. Current set up is the 2 27"s with a reconditioned iPad, the 24" is in the back room set up for audio.

As to when you should upgrade/change, you're not doing anything heavy; graphics, video, audio or games, so if the current machine is working for you and not pulling, then grand don't change.

But now is probably a good time, due to new machines coming in and shops having a stock of 'old' machines. Whichever, get 2 backup external hard drives and if u do decide to get a new one, keep the old as backup.
I'd say buy a new one when the existing one annoys you enough.

I'm a great believer of if it's not broke, don't fix it. But the camera on my current laptop really showed its deficiencies in the recent Zoom meetings so I'm scratching my head.
I bought a new laptop recently because the old one didn’t support virtual backgrounds on Zoom. Frivolous I know! But I’d had the old one for five years which seems reasonable (and am keeping it as a spare.)
If you have no working backup that you could use if your current laptop goes 'pop', then buy it now.

Always keep your data on an external hard drive. And back up regulalry onto another one. Do not keep them in the same place.

The biggest problem you will probably have is with software - most of it seems to be on a monthly fee basis now, rather than buy it for all time. And you may find that software you paid for in the past will no longer load, or require validations that you cannot do.

MSOffice I am looking at you here... anyone got any advice on alternatives? Open Office used to be rated? Not done any research yet (no time!), but have had a new tower system sitting on the floor for 2 months now.
Blue Witch - OpenOffice is still around but hasn't had any major updates for a very long time.

It's de-facto replacement is LibreOffice which arose from the ashes of OpenOffice. LibreOffice is very much under active development, and is a very competent office suite. It's open source, free to use, and definitely a very strong contender against Microsoft Office. Basically, you can't really go wrong with LibreOffice.
I started on the Commodore 64, before finally joining the PC crowd in 1990.

Everything since then has been desktop, assembled by me. Which means it's hard to say how "old" the PC is, or even when I got a "new" PC. My current desktop has certain parts from 2006, although the main bits are only about 4 years old.

As to when to upgrade... If you're on a 6th (Core i(x) 6xxx) generation or better Intel CPU, there's very little in an upgrade. If it's older than that, there's probably a fair bit of uplift - not just in performance, but battery life, thinness, weight, screen, ports, etc. If you've not got an SSD as your main disk, then a move to that is like night and day. This can be an upgrade to the existing laptop, or part of a new purchase.
If only desktops are counted I am on my ninth (also 5 years old), but if laptops are included my current is my thirteenth, although I also have a 10-year-old but still working laptop.

A few of machines I had used did make it to 8-10 years, but the worst only fared 1 before I had to replace the motherboard myself.
When is the best time to buy? I'd define what you want, and then keep an eye out for offers, and buy when there's a good one. Dell, for instance, will often shift out slightly out of date models at a hefty discount.

Kevin. I guess laptops are so popular because they can be put away much easier; used on the sofa; etc. I worked from home with my laptop on the dining room table for several years - at the end of the day, I put it in a cupboard - much cheaper than buying a house with a dedicated office.

BlueWitch, I'm not a big fan of subscription software, but when the Office family ediion allows for 6 users for £8 per month for all the office apps and a terabyte of cloud storage, I think it's pretty good value; certainly when compared to Adobe, for example.
If you don't need to replace your laptop then don't until it becomes a right royal pain in the rear to keep it going. If you can't complete your daily tasks with ease, get a new one. It's simple really.
Hardware-wise, mean time before failure (MTBF) could be interesting to look at, but figures are rarely available for entire systems, and of course, the individual sample under real-life conditions may be far off statistics.

As a rough indication, if your notebook has been advertised as a 'mobile workstation' and has an Energy Star badge, the manufacturer expects a MTBF of at least 13.000 hours (link). That equals to 6 hours per day for 6 years.

(My own laptop is 10 years old and forced into retirement later this year, when the newest available operating system drops out of support.)
Thanks Andrew Bowden for the LibreOffice advice.

Ian - thanks, but I would never, ever, ever, keep any of my data in 'the cloud', and I think that £96 a year for one person to lightly use Office apps (for personal use) is outrageous, when I have already bought the program on at least 4 previous occasions. I don't need a swanky new version, but none of the CDs of it that I have will now load as they all require email verification and they were linked to email addresses that no longer exist.
A lot of it will depend on how well specified the PC was in the first place.

If you don't count the Commodore 16 my parents ill-advisedly bought me one Christmas in the 80s, my first PC was a pretty well (possibly over) specified Dell in 1999. I got 7 years out of that before deciding to upgrade when I wanted broadband.

I then got six years out of a slightly less well specified Dell before the hard disk expired. The replacement for that lasted seven years before the graphics card packed up last year. I could have just replaced the card but other bits would almost certainly have followed and I wanted to upgrade my 2006 monitor.

All of which is a long way of saying six to seven years for me. I would suggest starting to think about what you might want next after about four or five to make sure you get the right one when you eventually have to buy something new in a mad panic.
Reminds me of school....."Answer the question!"
Best time is when there is something the present one cannot do, but certainly about 3 weeks before the present one dies and leaves you stranded. The science is knowing when the present one is going to die! If you could market that information for subscribers I suspect you might have a thriving business.
I'd say the right time to buy a new one is when everything you do takes a long time - booting up, saving documents etc. You could also improve your current laptop's performance in the meantime by adding memory cards up to the maximum (I think most sellers, especially independent ones, offer an installation service). Also, I definitely recommend swapping your hard disk drive for an SDD and use the HDD as an external drive - your laptop will be blazingly fast in comparison after that! Whatever you decide to do.
Great plot twist in the last paragraph.
The T430 and T530 were the last true ThinkPads. As you can pretty much change every component they may even least longer than your T550. They're the complete opposite of modern laptop design and are built like tanks
I second what Jon Combe wrote about leaking batteries.

The damage from leaking batteries can be so bad that it's worth removing them with just a wire cutter if desoldering isn't an option.
Wonderful to see that you're part of the Thinkpad club. Honestly if your T550 is still working it's a great machine and there's no reason you shouldn't keep it for the foreseeable future.

As for your RISC PC, you'll want to take a look inside it. The internal battery might have leaked all over the motherboard. It's a nasty problem these tend to have. If it's not too bad it might be salvageable but in any case cut out the battery for now until you have chance to solder in a replacement (or sell it to someone else who will do so).
