Is that server or desktop? I can believe it has almost 25% of the server market, but no where near that amount for desktops.
For Linux to heavily break into the total marketshare it needs to get more agressive in the desktop arena, not just server. I agree with your statement "I think the future is now, with OSS and closed source in the same echosystem". In just the last year that we've been on this thread I've seen Linux make some impressive moves and gains. The future for Linux is wide open and limitless
And for that to happen, they need to hire people other than programmers to handle the ergonomics and feng-shui of the whole desktop thing.
As much as I like KDE, I can point to several examples of things being way harder than they need to be, or the obvious is not pointed out because the programmer assumed you knew more than you did.
Linux definitely has it's merits, but the desktop environment people need to get their act together to make things a lot more straightforward.
Oh yeah, and NB4GE.
