Besides the whole touch silliness, the Metro UI looks basic & childish... it looks like a PlaySkool or Fisher Price product. The "tiles" looks very simple and boring looking. It looks like a extremely low-level freeware package.
I can't believe they are doing something this bad. From a person who has never used, touched, or even seen (except on TV and online) a Mac... if this is the way Windows is going, I'm ready to switch right now to an extremely overpriced Apple machine.
