It seems MSI couldn't wait a few weeks for Computex 2010 to unveil an interesting twist on the oft-used term "convertible laptop." The company showed its SketchBook convertible notebook prototype during an event in Amsterdam - but it's not just any old convertible. Rather than doubling as a tablet PC (such as Apple's iPad), MSI's concept machine features a rotating base with a keyboard on one side and a full-size graphics tablet on the other, according to Engadget Spanish.

Unfortunately, the display unit was non-functional, but the gadget blog says the machine feels bulky. Although MSI hasn't specified a market for the machine, it's fair to assume the SketchBook convertible will mostly be aimed at students, hobbyists, and possibly even graphics professionals - all of whom might appreciate a rugged design, so perhaps that's part of its heft. Regardless, since this is an early reference piece, the company might trim down future builds.

No price or release date has been mentioned, but the system is expected to appear at Computex, so additional details might be shared then.
