(Reuters) - Nokia sold less than 100,000 top-of-the-range N900 smartphones in its first five months on the market, researcher Gartner said, indicating it has yet to mount a serious challenge to the iPhone and Blackberry.

The N900 is not a mass-market device. Nokia's been very clear that the N900 was launched as a means to strengthen its Maemo development community (on the path to MeeGo we now know). Update: While Nokia doesn't normally give out detailed sales figures per device, we've just been told that more than 100,000 N900s sold in the first five weeks -- not months -- globally.
