Agreed, although for less technically inclined folks, moving to Linux would be easier. Seriously, drop Lubuntu on their formerly XP machine, get them over the hump of using a new OS and web browser, and they'll have far fewer problems over time. Plus less technically inclined users tend have less holding them to Windows: My mother used Lubuntu for the last 3 years of her life since the only programs she used were solitaire and a web browser, but I can't move to Linux due to a lack of games, needing Windows for school, and potential hardware compatibility issues.
You know what rustles my jimmies? When people say there aren't any good games on Linux. ;)
Agreed, it is a lot better than it used to be and when I build my desktop it is very likely that I'll be dual-booting or running Ubuntu exclusively, at least for a while.
