"Why remove the charm and usability from Windows, in the mad chase for apps?"
That's the crux of all Windows faults. They have forgotten the OS business that gave them such a large market share and are chasing a market they don't understand. The desktop experience and what people do with phones don't need to be identical--which is an impossible goal for any decent functionality on either group of devices.
Apps are apps because they are lightweight applications that work on phones. But nobody wants a crippled desktop because its been reduced to phone functionality.
What would really be wrong with a desktop OS, a decent tablet adaption and a phone that works?
