Ive used Windows all my life, 3.1 followed by 95, 98, 2000 and now XP, and Id describe myself as fairly competent at working with it: so anyway, this would be a pretty new experience for me.
Read it here and enjoy the conclusion:
Im definitely going to stick with it. The impression I definitely get is that although it may not be the best OS for gaming – or, the limited retro gaming Ive tried so far – it certainly beats Windows in terms of speed, reliability and aesthetics. There seemed to be open source software for everything I needed to do, and I didnt have to compile or manually install once.
