Charming Man, your talking about linux (basically :P). If it had more attention, it could be so good. Lack of support from Adobe is kind of a stopping point for me, though I love it to death for coding and regular programming (read:school).
I am about to buy a Mac myself. Had the chance to use OSX in school, and I really like it. Actually, because its more similar to Linux than Windows, and much like Linux, the way things are done seems to make more sense. The OS seems to cater to the technically-minded people while keeping things nice and clean.
I can't find a windows notebook that has the same specs as a 17" Macbook Pro for the price.
