A lot of 7 year old computers are still totally usable, PCs aren't advancing like they used to. My 2012 retina Macbook Pro is a little bit slow in some cases, but it's still a great machine for normal tasks.
Yeah, I actually bought a 2011 MBP like 2 years ago for 200 bucks. Use it as my main driver for my home music studio. Big projects load a bit slow but aside from that everything works fine.
Only thing I don't like is that there isn't really a cheap and decent way to have 2 external monitors on it AFAIK. Which is why I built a low budget Ryzen 2200g build which is perfect for audio and coding and now share my work between the two.
Yep, threw win10 enterprise ltsc on a 7 year old laptop. Use it as a media player sitting under the TV.
