All I have is a 13 year old laptop, and I use it basically all day most days. It's plays music and movies etc with no issues. Cloud pc for gaming, which also works perfectly. It really doesn't like youtube, though, and it sounds like a jet engine every time system and app updates start to download. Can't afford to get anything better anyway. A friend gave it to me after it died on him and he got a new one, wasn't hard to fix. I cried when I got it because it improved my life a lot, just being able to do basic things.
I love watching videos about plane crashes on my old tablet when I'm cooking or rinsing (non-native here, is that right for doing a dishwasher's job by hand?).
A heads-up to anyone running old laptops; buy genuine replacement batteries while they're available!
I have an aging XPS 13 and of course, Dell have discontinued the battery line. Opened it up one day and every cell had puffed out. It took buying a couple of fakes before finally finding a decent reseller on eBay who stocked what I needed. The fake batteries were not recognised by Dell's hardware detection system thing, I imagine lots of other manufacturers might implement the same feature.
Old laptops will still run pretty good if you run lightweight Linux distribution and give it some RAM upgrade and maybe SSD as well. I still wouldn't use them as my main computer, as I'd rather have a lot better specs and ability to run Win10/Win11 flawlessly, but it's still a good option.
17 year old Dell here. Threw a SSD and Linux on it and that damn thing boots faster than most brand new Desktops. Absolutely enough to surf the web, listen to music, watch videos or do the usual Linux stuff (ssh, etc.). You can even somewhat game on it via sunshine/moonlight.
This is very well timed for me. I just acquired myself a convenient ancient laptop by installing Linux on a circa 2014 chrome book. It can chug when playing videos, but great for general use.
This is me with my 11 year old thinkpad t420, sometimes I'll even ask it to play minecraft or holocure both of which it will mystically play just fine
Steams interface unironically runs worse on it than those two games
My 2014 Toshiba i7 still chugs along. Technically it's two laptops in one as the first one if it was rebooted while hot the GPU would go all 1024x768 in the top left corner. The replacement mainboard I got ended up being an AMD one but if I enable the AMD chip in device manager it simply dies so it uses the onboard Intel HD graphics instead.
1GB SSD, plus 2GB HDD in an optical bay adapter.
It's on its third battery - works for about an hour but jumps to 7% within a minute of running on battery, so if I put it to sleep etc it won't go again without power.
The first (and last) surface product I bought was the pro 3, and I still find uses for it today. I'm planning on making it a media hub for my workout machine when I get that set up. I need to clear some space before I can put that together.
I recently purchased an older gen (refurb) framework 13 and it sure is quick. A bit costly, but hopefully the last full laptop I'll need to buy.
My desktop is an older (purchased used) Dell high end desktop system, which I dropped CPU/RAM/SSDs into and augmented with a Nvidia RTX card. Runs like a champ. Built in ~2016 or so... It was like 5 years old when I got my hands on it.
I still have my ~15 year old Alienware... I think the M15x, which was a pre-Dell acquisition laptop. From college. Which still works but probably needs some coaxing to get up and running again. That was the last "new" system I purchased. I learned my lesson then to not buy new.
I also have a collection of older servers and stuff and I run a homelab on dated enterprise equipment. It needs an upgrade as the main components are over 10 years old (except the drives), and it's showing its age. Looking at getting a refurb/used Dell FX2s chassis because it's more upgradeable than the alternatives and should save space and power.
The only warning I will give is that low end consumer systems are going to be garbage, whether they're new or not. When buying a used prebuilt, I highly recommend finding a used business system.
The magic of a ssd and a lightweight distro running xfce can even perk up an average system from 2010. Bonus points if you can upgrade the memory. You can probably still get to a login prompt in 20-30s, and cold boot to a link saved on the desktop playing music in under a minute.
That's about $30 USD in parts. You will probably struggle with more intense tasks. We just replaced desktops with similar specs that were just barely able to run optimized Minecraft a couple years ago.
