a mouse and trackpad option would be great.
Or the other option is to make this run OS X and be like a surface tablet and also run IOS apps.
A mouse and trackpad mean a cursor (or any kind of drawing tool). But moving a cursor if no mouse or trackpad is connected on a touch screen is a bit of a pain (as we know from text entry on iOS and other touch-based OS).
How is that solved on the Surface? Is the cursor only there if you are in the traditional Windows environment and it disappears in the tile (Metro) view? Or does it disappear when you unplug the mouse or trackpad? Or does it only show up in text fields when using the Metro environment?
