My rule of thumb has always been, get something from a major manufacturer that is not bleeding edge, so I can be sure driver support is there. That has served me well, and I also usually buy devices that area certified for Linux. That being said, Ubuntu has really jumped the shark and I wouldn’t be surprised if this is the result of someone messing up some snaps in some way.

Gnumeric, not because of it’s features but just because it’s so ridiculously fast
