On a side note, slick website followed up with crap video.. really? An impromptu interview with a haphazard overview of the software & bad audio is the best they could come up with? Maybe its just me, but I'd like to see a little more effort & clarity in the marketing..
Update: I tried the free version too.. if you've got an acoustic and an i-Phone it works well as far as picking up the guitar notes. It is exactly like Guitar Hero as far as I can tell.. kind of fun in a way, but it also indirectly encourages you to blunder through as best you can, and then try again to "improve your score". I was always taught that the fastest way to learn something on guitar is to practice at a speed where you make few, if any mistakes, and then speed up only when you can do so & still play correctly. Still, I'm curious too.. I tried to check out what the upgrade costs, but it said it was currently unavailable. I certainly wouldn't trade this app for one of Lisa's or Christopher's lessons, but would be really interested to hear from anyone who feels they're getting somewhere with it.
