Where Have I Seen This Idea Before?

BoyGeniusReport.com has a picture of a Research In Motion BlackBerry keyboard patent that shows a drawing of a BlackBerry Pearl-like device with a fold out keyboard.

Interesting that this photo surfaced. Didn't we see an "unidentified" smartphone that transforms to allow you to use a hidden keyboard? I wonder if these transforming phones are all the rage in smartphone OEM developer circles?
