Did the train move or the platform?

Is the keyboard attached to the phone or the other way around?

People keep talking about "the N900 keyboard sliding by 40%", but in fact it is the part with the keyboard that is the base and it is the display that slides out.

It does not matter if the OH is "too heavy", if you hold the whole assembly by the OH. Then it becomes the matter of how heavy the phone is instead.

Having a sliding keyboard on plastic clips like the N900 back cover is a serious concern IMO. It may even be a showstopper, unless they (we?) find a way to bolt it to the main chassis.
