I would not want that to come with the unit. Maybe if the unit had an expansion port to lock into or just some bare contacts that an optional (read: buy seperately) device like an e-ink case could touch or communicate with with you slip the N9x0 device into it? Maybe if they moved the USB port out from behind the kickstand and just used that for the case to click into? (I might be afraid of damaging the port if the case gets dropped with the N9x0 inside.)
