Guitar neophytes looking to learn guitar without having to practice should check out the TabStrummer. The TabStrummer is a literal keytar -- a guitar made using computer keys so that it's easier to play.
The TabStrummer features 12 keys that are each pre-programmed (or can be programmed) to play all of the chords of an electric and acoustic guitar. Despite its unique design, the TabStrummer at least looks the part of a guitar, albeit with a plastic body and a neck filled with computer keys. The guitar has a MIDI out connection so that you can plug it into your headphones, an audio jack or a television. The TabStrummer is currently unavailable for purchase, but guitar newbies such as myself can always dream.
