IMO windows 8 will be another vista it is horrible in usability, navigation, use, fuctions and just about everthing else a user needs in an operating system. I posted it was cool and growing on me months ago, but the more I used it started to become a monster.
I wasted so much time trying to figure out how to move about it was over for me. I deleted it and will never ever in a million years ever for any reason (well maybe a million) think or fart the idea of installing it on any machine excet the 1999 one I own. Then again my 1999 machine has a 500mg harddrive and you need about 3g for the install.
I predict it will sell like hotcakes.. because in the end, even Vista was profitible and the big problems with vista weren't fatal design issues but abysmal hardware support and cheating OEMS selling crappy computers.
