I don't know about you but I really don't want my laptop to be the hottest thing, it sits on my lap.

My thinkpad is from 2017, but I bought it in 2022, it's still working fine - I upgraded the memory to 32G (£70) and I've replaced the battery twice (once when I bought it, once a couple of months ago). When I replace it it will likely be because of hardware failure (droppping it etc).
