how do I sign up for pre-order or at least put my name on a list for when its available?

btw, for those worried about the keyboard falling off - is there a way to put in some sliding gutters that hold it in place permanently and only lock when you slide it to the magnet positions? just an idea anyway. but that would mean the keyboard cannot be swapped with other keyboards or gamepads.

the gutter would be like curtain rails e.g. http://www.goelst.com/uploads/images.../6200/6200.jpg - see how the hooks are attached to the rails? they cannot be removed. but it would also make the other half cover thicker...
