Quote - from what I heard, vista is a copy of mac os 10.2 and 10.3, but to get all the features, ya gotta spend $400 u.s.

 

You heard wrong. Vista is based on Windows NT/XP, but with a lot of revisions to the core Operating System. There are also a lot of bells and whistles in the User Interface, and an ill-considered emphasis on Digital Rights Management. Mac OS 10 is based on Mach which is in turn based on Unix.
