The LG Versa incorporates a novel design: a removable QWERTY keyboard that's built into the case/cover. Reminds me of some of the early Tablet PC models that incorporated a detachable keyboard for the times when you need to do a lot of typing. Then, you can remove the keyboard if you need to carry the ultralight tablet around all day.
The engineers at LG may be onto something exciting here. Imagine what could be done if Apple also copied this design and created a case/keyboard for the iPhone? Samsung with the Omnia?
