This simply isn't true. They are still cheap even for decent stuff. I got a T15 Gen 2 when it was 2.5yrs old for about $400 on eBay. You're not going to get an even remotely decent laptop in most cases for that kind of money. And to be clear, I love old Thinkpads. I have them going back to the IBM days.
Modern Thinkpads: -easy to work on -plenty fast for most things -still made of the carbon composite and magnesium chassis we like -hinges are beefy -upgradeable ram -available with GPU -lighter and easier to daily than any of the old chonks -replaceable keyboard, track pad and track point, and fingerprint -dual thunderbolt connection (and docks are stupid cheap.. I find them for $30 sometimes)
Downsides exist but they're not the end of the world: -one drive slot (drives are huge now, who cares) -8gb of RAM is soldered but the rest is not (max 40gb) -internal battery but laptop is faster and has better battery life than my maxed out T580
OP what makes you think you're not? This post is autistic AF, as someone autistic.
I'm very high masking when I choose to be (sometimes when I'm not.. it's sort of automatic by nature at times) and in a lot of cases people never know. I was in my 30s before I figured it out, and I used to use the saying "I'm not autistic but" a lot.
There are free tests available. AMA (not a pro but I have over 30yrs experience!)
