Been running Linux Mint on this ThinkPad A485 for 1.5 yrs, problem-free. There is no feature that doesn't work. Even the media keys and stuff like the wifi-toggle function key work. Still, yeah, there are some things that are perennial problems for open source OSes, particularly wifi. Nice presentation on the topic: "All types of wireless in Linux are terrible and why the vendors should feel bad" @ https://www.youtube.com/watch?v=pwIFz9na2lE
