i made the switch to 11 in november 2021, had to make some changes to the ui (the right click menu is awful) and uninstall all the ad apps , but so far so good...
out of the box is fucking terrible with pops for everything, but once you dial the right settings its pretty reasonable and stable, i would say the most stable Windows i used since 3.1 (one bsod so far in 3 and a half years and i think it was my fault)
in the T60 i have Mint 22 x64 with XFCE, i had to babysit that MF more times than i wanted to, getting ridicoulus messages with ZERO explanation of what is happening (Make work something out of the ordinary is a pain in the ass most of the time). The very thing that an OS has to do is not getting in the way, and Linux is not there YET
and all this is coming from an IT guy of 26 years in the field. If i get frustrated with stupid shit that make me feel im using a house of cards like Win 98 SE, i cant imagine a normal person in the daily basis with this.
and man...its Mint, one of the friendlier distros. The only thing going for this kind of distros is that out of the box is pretty usable with all the common stuff to use, unlike windows that its pretty useless
