lol, it is Apple's OS just copied into Microsoft's programing.. Its just like when Apple had started, and Microsoft just said "Hey, lets just copy their code change it a little and say its ours"
Vista is also supposed to have a Higher Demand of Processor and speed and stuff (so i've been told).. All in all, if i were to get Vista, i'd go run to CompUSA and grab a Mac, along w/ some OSx and some Apple games >.<
-----My Opinion is that its a rip off, and sometime Microsoft just put together very fast to compete with Apple, and Linux (don't forget Google OS. jk) It was also supposedly worked on by a US Gov't agency, that placed secret files in it (Microsoft has this in Windows XP as well but different than Vista -
Microsuck)
Grade for OS: 1/10
