Auto-Tune for Guitar

Joe Gore at hipped me to the fact that you can now get Auto-Tune for Guitar as a kit. Like him, I thought it was just to help keep guitars in tune—a problem some of us haven’t had for years. It seemed excessive to process the guitar sound through a hex pickup  rather than just get a good, well set up instrument and learn how to string it and play it in tune. But this video shows other interesting and potentially creative uses. it also shows that you can still play out of tune if you want. What do you think?
