Air Guitar Pro can be strummed, with no strings

No really, it can, there is an infrared sensor. There are also fret buttons, a built in speaker, media input and output ports, volume controls and 10 songs that come pre-loaded.

There 7 buttons for CDEFGAB keys. There are also buttons on the top for major, minor, augmented, and diminished scales.

So, press the right key in the right scale, then "strum" your fingers past the IR sensor and off you are, rocking your way to Detroit Rock City. You can even hook up external audio sources like your iPod and jam along to the music on there. Also, if you aren't a big fan of the whole world being able to hear your l33t air guitar skills, you can hook up some headphones.
