hmmm
- create some "on the desktop buttons" maybe on the Object Bar" to show things like the Metro Interface, the Charms bar, or the currently runing apps. I dislike having to move mouse around to find hotspot in the corners of the screen.
- make sure that Microsoft Store Apps, will show up on the Tiles bar and you can individually close them, intead of having hundreds running after a while like on my iphone. Heh, how about a timer you can set if the app is not used for more than 5mins then it could be closed automatically.
- defintely will nheed a customize option or app to reorganize and retranslate the Metro Start Screen.
Oh, and i do use a regular desktop PC, with a regular monitor and mouse, NO touch screens, yet anyways. 
Thanks
