Mobile analytics firm Flurry says Google's Nexus One is a sales flop. Using estimates based on usage of its apps, Flurry believes that the new Android-driven smart phone debuted to dismal sales.

The same metrics show that Motorola's Droid launched to better-than-expected numbers, selling over one million units faster than the iPhone did when it was released in 2007. Flurry does note the Droid had the benefit of coming after the iPhone, a device that changed users' perceptions about the capacity and capabilities of mobile devices.
