Flurry reports that sales of Google’s Nexus One haven’t even come close to sales of the Motorola Droid and the iPhone, with each beating out Nexus One sales by about eight times.

The mobile analytics firm estimates Google sold just 135,000 devices within the first 74 days the handset was on sale – the same amount of time it took to sell 1 million iPhones.

Google’s online-only sales strategy, combined with poor customer service and early reports of device glitches, appear to have hampered sales of the device, according to a report from Goldman Sachs that came out last week. Goldman Sachs estimates Google will sell just 1 million Nexus One devices by the end of the year.

Flurry also reported that sales of the Motorola Droid outpaced sales of the iPhone during its first 74 days on the shelf. About 1.05 million Droids were sold after its November launch on Verizon’s network, compared to the 1 million iPhones that launched on AT&T’s network within the first 74 days of its debut in July 2007.

Flurry attributed the figures in part to Verizon’s larger subscriber base, which was at 89 million when the Droid was launched. By comparison, AT&T’s subscriber base sat at just 63.7 million when the iPhone debuted. Also, the Droid was launched during the holiday season with at least $100 million of advertising support.
