You don`t have too,When i had my iPod 32 gig it was the same as a iphone4.All my IPod needed was a bios flash to make it a phone....Microsoft sees this and is doing the same thing,And all who use Win7 are H8ting on that fact.Fact of the matter is I seen all The Vista users here Bitch Win7 was a refresh why bother,Imagine What would have happened if Win8 was just a refresh????? 1,Apple 622.45 Billion made (Also beats Microsoft's best year 99) 2,Microsoft 534.42 Billion made Wonder Why Apple has an upper hand these days???? They have one Os for everything mobile And there mac-os X .That`s Less money spent is more money saved and earned. Boy now I can not wait for Win9 to come out and see all these START Button guys complain even more.What gets me is they don`t even realize all them Win7 updates the other day are from Win8.....Go figure why we installed a More Secure OS. Oh And Whizz Thanks for the great review.
