While I agree on the application side when I say GUI I mean right out of the box. Gnome ain't that pretty until after a bit of customizing, And I use gnome.

With Software Developers seeing this business relationship they will start to follow.
Open Office is a nice comparable solution for Microsoft Office the part where Microsoft dominates is Outlook. If Outlook was not part of MSOffice, Open Office or even Star Office would be much more popular.
Wine is ok, crossover is better, but I agree running programs natively is the best way.
