Nintendo DS, effective piano instruction requires at least twice as many keys -- and an iPad. The Ion Piano Apprentice (when coupled with a compatible iDevice and companion app) offers aspiring Tchaikovskys octave-selectable free play, lessons on reading sheet music, and even a view of award-winning piano instructor Scott Houston's handsome hands. If those mitts are too distracting for you, just follow along with the light-up keys, you'll be fine. This mini keyboard / iPad dock will land this fall to the tune of $100 -- -- it's either that, a real instructor, or a pair of haptic robot gloves. Your choice, really. Hit the PR after the break for a peek at Mr. Houston's official nickname, if you're into that sort of thing.
