I don't buy into the Stallman/socialist all proprietary software is evil outlook though. I realize Microsoft may not be completely anti-competitive and use questionable business practices as the norm either. I like Linux 'cause it works, period. No muss, no fuss.
(*) Admittedly not 100% MS free. I still need XP once in a while to: load updates to my DSL modem; run the software that came with my Garmin GPS; load my wife's iPod; load my Samsung T10 MP3 player. All claims of the Linux community to the contrary, while I should be able to put music on the iPod and T10, no luck. No luck running their software under WINE either.
