RIM flexed their creative muscles with this hybrid, throwing in a concealable keyboard to boot, with the patent describing the idea as follows, right after the jump.
An electronic device having a concealed keyboard includes a first housing, a second housing rotatably coupled to the first housing, and a concealment cover coupled to a rear of the first housing. The first housing has a coupling edge and two sides that are substantially perpendicular to the coupling edge of the first housing. The second housing has a coupling edge and two sides that are substantially perpendicular to the coupling edge of the second housing. A receiving portion is formed on a rear surface of the first housing and is configured to receive the second housing. When the second housing is in the receiving portion, each respective side of the first housing and the second housing are co-terminal with one another. The concealment cover is exteriorly positioned with respect to the second housing when the second housing is in the receiving portion.
Well, if RIM has a keyboard-less smartphone in the works, who are we to say that they will not introduce a tablet/laptop hybrid with a concealed keyboard down the road?
