Take one MacBook with a 13.3-inch screen. Remove the keyboard. Replace the plastic LCD screen with scratch-resistant glass. Add Wacom graphic tablet capabilities, Apple's Inkwell handwriting recognition software and a digitized pen. Voila, the Axiotron Modbook, a Mac graphics tablet that graphics designers and other arty types are going to drop their T-squares for.
As far as we know, this is the only Apple authorized Mac that's not sold by Apple. It's available in several configurations, but the basic sets all include GPS capabilities for reasons that escape us – what does GPS have to do with graphics design? In all events, a 2 GHz processor version runs $2,290 and a 2.2 GHz engine is $2,490.
Yes, you could add on a keyboard and a mouse and turn it back into a full Mac, but that's be like removing the music from My Fair Lady to turn it back into Pygmalion.
