The Metro UI is focused for Tablets, Phones, TVs and Kiosks, not for desktops and Laptops you dope. 99% of Desktop and Laptop Windows 8 users are going to go strainght into the the Desktop mode, (aka Windows 7) not stay in Metro. Surely that is pretty obvious. Why do people seem to think that Microsoft is trying to impose Metro on the Desktop users ?
Metro UI is really pleasant and innovatibe to use on Phones, and providing we get quality Tablet devices, it looking very attractive consumer and Professional Tablet experience to compete with iOS. What will be interesting is to see what subset of Office 15 will be useable on Tablets and Metro UI, and how these comapre and interoperate with the full Desktop Office versions.
