You are pretty lucky if you haven't experienced any issues. For most people thogh spots are gonna be:
-
Gaming. While a lot of games work perfectly a lot also don't work (mainly if they have a
kernel level anticheatrootkit) -
Nvidia. Do i have to say any more?
-
Wifi. Often wifi cards just don't work or work very poorly.
-
Laptop specific features. Stuff like a MUX switch, ambient light sensors and fingerprint scanners very often have no drivers for linux.
