This looks like a potentially really useful tool, for performance and/or practice. It's just getting off the ground, and I am installing it on my Droid smartphone, only $6 bucks. Should work well with BIAB, and all the new Apple and Droid tablet computers and ereaders popping up in the near future. 900 built-in leadsheets, and lots of additions from the user base.

From the web site (www.irealbook.net) "iReal Book is an app for iPhone, iPod Touch, iPad and Android that contains a collection of hundreds of chord charts of jazz standards, jazz classics, latin, brazilian, pop classics and more."
