Just wanted to share something I stumbled across while researching this for myself. It is a
Sales FAQ from one of PG Music's international websites (scroll down to item #6). They give a short description of Band-in-a-Box, PowerTracks Pro Audio, and RealBand; and then follow it with a feature comparison chart. The page was last updated Nov. 21, 2010, so not sure if it contains the latest features, but it is still great stuff!
I wish they would include it on the .com FAQs.
