There is, of course, the iGuitar or the Pocket Guitar, each allowing you to play any song a physical guitar will allow you to play, but fitting into your pocket much easier. But what if you took two or four smart phones and set each of them up to do a different musical task, and played them all together? Rick Wakeman used to need 400 cubic feet of stage space and a dozen hours per show to assemble a fraction of this audio power, and that only after a crew of teamsters moved, mounted, and bolted together the gear for him. Today it can be done by a single girl with four smart phones, one for voice processing and the others to do the band instrument parts. The Futures so bright, I gotta wear shades!
