Metro is an abortion in my opinion. How cool to touch huge, squarish buttons... then what????
Who would pay you to srf the net, or open apps? Real world activities require interacting - and I mean, really interacting with the interface. So, your chubby finger opens up Excel. Or the ERP of your choice. Then what? Sure, you need a mouse a KB and lots and lots of resolution to get work done.
When I look at Metro's interface, it looks either like a child's toy or an abstract painting. By no stretch of immagination is that a day to day interface. So what if it runs on 10 flavors of hardware (that I'd never get to use) or off a mem stick - IT would drop dead before users are allowed to boot the OS off a stick.
Really - this is an attempt to have something that works off a slate or smartphone... but I would not run that off a laptop.
