Re: I used to be like you
Can you use what application/service/game under windows?
Lets be clear about exactly what isn't availible under linux yet - recent windows games(relying on latest gen gfx cards) and even then many devs who are not hog tied by MS have already moved their stuff across to one form of linux or another. MS are no longer the leader in anything except spin, marketting and threatening litigation
Every other standard application type is more than covered and more than likely free/open source.
In truth the needs of the majority of PC users (office, web browser, email client, media player etc) tend to work better under linux, so games that are legally tied to MS might take a little longer to move across
In Summary
-----------------
Those few people who actually get paided to support windows gamers might get to say "No they haven't made a linux version (YET)" but not very often and not for long.
