I don't want to begin a Flamewar (hello, everyone <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> ) , but in my opinion the stress has been put too much on Linux as a server system.
I know that there are Lindows PC's out there, but here in Germany one of such a kind is rarely to be seen; the people rather buy Linux (for example the SuSE Edition) and install it on their own.
But I strongly suggest that a discussion about the position of Linux should rather be made in the Chat Section, not here.
