Retail research kingpin the NPD Group is reporting that Android-based phones are now outselling iPhones. Or at least they did last quarter in terms of unit sales in the U.S. according to NPD's study, which found that RIM's BlackBerries held 36 percent of the market, phones running Google's Android had 28 percent, and the iPhone was at 21 percent.

It'll be fascinating to see whether Android's unit sales edge persists-and grows. (There are new Android models every month, but some iPhone admirers are presumably waiting for the next-gen iPhone which will likely be available in June or July.)

Will Apple feel forced to respond to the Android explosion with price cuts, the introduction of budget-minded new models, or other moves that could steal back marketshare? It's not a given. Between the iPhone's healthy pricetag and the walled-garden megamall known as the iTunes Store, Apple is perfectly capable of being the most profitable smartphone company even if it doesn't sell the most phones.
