Is linux really that much more stable, quicker & simpler to use than windows to warrant switching, bearing in mind the compatibility issues?
I know everything can be run in a windows shell, but that would defeat the benefits of having an efficient & stable OS in the first place?
depends on what you want to use it for...
For day to day stuff - i.e. going on the net, listening to music & watching videos, msn/aim/yim/irc, spreadsheets/wordprocessing etc, yes it is there now, very stable, very fast, and has been for about a year, my preference is to use linux for that machine that I do most of that stuff on.
Also for programmers i think it is a slightly better OS to work on (unless you are writing windows programs) because i feel there are better productivity tools for that area.
I think the biggest hole right now is support for windows games, while Wine/WineX and Cedega help a lot they are really just emulators and aren't perfect at all which deters a lot of people.
The same applies for a lot of graphics/3d/production/video software as well.
Linux certainly seems a lot more stable in general, it is very very hard to crash the whole system (i.e. equivilent of a windows blue screen), and a lot of distros will run on more varied hardware than XP or Vista.
