To clarify: I am most interested in option #1 above.

So... as a one time procedure can I then view and playback my BIAB files previosly made at home without a connection? Again I would like to use Android as a playback device and viewer for my files when performing them live. I need to check out the demo video above but this would appear to be a break thru application. A friend has a Fakebook app on the Iphone which we have used on occasion for transposing tough tunes like Ipanema when some one wants it in a key other than F.

Again viewing and playback alone would be enough to get me to purchase an Android and leave the laptop/binder at home.
