I'm pretty much gone over to Linux entirely, though I can call myself a Microsoft Professional if I want to, having passed a few tests. Linux drives me crazy at times because it is so much trouble to fix problems that have known solutions, and some people act so superior because they happen to know the name of some file that you have to edit or that such and such a fix can be found in such and such a place, or that the correct syntax for a command is "this" and not "that".

Fortunately, some distributions exist that try to minimize these problems.

BTW: I think that the basic premise of this thread is false -- I don't think that Linux is particularly "held back". I think it's thriving.
