The windows 8 tablet/phone/operating system will be an gigantic flop. The tablet is too expensive, looks like a PC product (ridiculous kick-stand, pointless keyboard), and doesn't have nearly the apps. The computer operating system is a major upgrade, but who cares to upgrade their PC OS? Especially if it's a dramatic change. I'm guessing people will prefer to stick with windows 7. Windows based PC sales are declining, Apple is the only computer maker gaining sales in that category.
I will hold you to that. I expect Windows 8 + WP8 devices to be flying off the shelves by Christmas with no end in sight.
