Taken another way, this campaign would have clearly been -ROI if the Piano apps themselves ran it themselves. Although a mass-market television commercial clearly isn't the best way to reach a niche audience, I think it definitely says something about the market potential and profits of most apps these days.

For sure, but I'm pretty sure Apple has been happy with this campaign. Not only did it result in increased iPad sales, it has increased app sales and iAd impressions, from which they get 30% commission.

The #2 iPad paid music app right now is a $10 app! That developer also owns the #1 iPad free music app. If I were him I'd be buying a plane ticket to Hawaii right about now. :-)
