And just a small opinion/addition/suggestion: if the sliding mechanism is durable enough, personally I wouldn't mind if the keyboard covers the camera. This means the lens CAN be protected, unlike with the currently known OHs, and although you have to open the keyboard when you take a picture, this also means possibilities of keyboard shortcuts for camera settings and operation like we have in N900+CSSU. I know, this can also be done with a hole in the keyboard, but I want to point out that not everything about having an open keyboard during camera operation is bad, and it would make the general design (and specially the key layout) much simpler.
