not one expects it to be a windows killer, its proving it could possibly be, i do gfx and music on my linux workstation along with gaming, managing my fininces and some programming/dev work, for people to say it offers nothing more than server apps shows that those same pople have no true standing experience with the OS.
I can do any and everything your avg power user can do on windows. YEa the quality of the app, desktop/workstation class, is going to be lesser quality functionality for the most part “out of the box” so to speak, but thats and issue when you have millions of coders practically doing projects as wide spread as it is, you get a flood of apps some good, most sub and a few really great ones.
And as for preformance, something like redhat is probably not the best distro to judge, as it does try to mimic a windows environment and does assume the users wont know/or care much about the going ons of his OS for the most part, so out of the box its bloated. I get stellar performance out of my installs
