As much as I'm fan of Thinkpad and I hate the idea of buying modern laptop, I don't want to buy a decade-old laptop. I just want a modern-ish laptop with decent CPU and easily-replaceable battery, upgradable RAM and SSD. That leads me to Framework laptop (but it is so much more expensive than buying old thinkpad). Thinkpad T420 is already showing its age and is too slow to run some modern or cpu-intensive apps (I wish it weren't true). Also, eventually ARM cpu might take over the x86/64 cpu, and when that happens, I'd be sad but the T420 would be relegated to running Home Assistant or for playing retro emulation.
