One screen good, two screens better. That seems to be the thinking behind one of Samsung’s latest awarded patent filings, spotted in the USPTO by Forbes. The patent shows a clamshell design not dissimilar to the Sony Tablet P, but using a larger, flatter form factor that’s more like a traditional laptop in shape. Also of note is a removable controller/pointer that slides into a slot along the hinge.

The last detail points to a device aimed squarely at the business class, something that Samsung has yet to do with its tablets. The dual 7-inch screens work separately or in tandem. Thoughts of a dedicated screen for a projector view and one for presentation management seem like a natural extension with the pointer, though it could be something a little more boring, like having a dedicated screen used mostly for displaying the keyboard.

This is hardly the first time we’ve seen a dual-screen design for Android. Among less commercial examples there’s the Kyocera Echo, which didn’t turn out so well. It must be said that there’s no guarantee that the patent points towards an Android device – dual-screen Windows laptops aren’t unheard of either. In any case, we’ve seen no indication that a “Galaxy Tab Dual” is coming down the pipe any time soon, but a guy can dream.
