The thinkpad was pretty good, and wayland on fedora worked beautifully (I only used integrated graphics in linux, didn't even try to get the discrete gpu working). The one thing that really didn't work in linux was the fingerprint scanner - it would fail about 7/8 times I used it, which is really too bad because fedora has really nice fingerprint integration with sudo.
Also, something seemed to be a bit funny about it's displayport implementation - when it was connected to my DP monitor and went to sleep, the monitor would wake it back up again almost instantly and it would get into this weird back-and-forth between sleep mode and waking. That happened in both linux and windows. This doesn't happen with my new xps.
Otherwise it was pretty smooth sailing. It was a well-built computer with a nice keyboard. I might get another thinkpad at some point, but I'm loving this super-compact 17" 16:10 display on the xps.
