I also think the Rod Stewart "Great American Songbook" albums have reopened doors for the younger generation to the great music of the past. I think it's a backlash against the trash that broadcast radio is so fond of. I play to people young and old today and get requests for old standards from both.

Back to the topic: I think there is a market for an Acid keyboard - that is, an arranger keyboard that uses Acid-ized loops specifically. So many people use Acid and Fruity Loops and Garage Band for making quick and easy music now that I suspect we'll see a keyboard made for loops someday.
