Currently, on Amazon.com, the N800 ranks # 28 in "Computer & PC Hardware", # 8 in "Handhelds & PDAs", and # 20 in "Notebooks". The N810 does even better at # 20 in "Computers & PC Hardware", # 6 in "Handhelds & PDAs", and # 15 in "Notebooks".

On Buy.com, the N800 and N810 hold sales ranks of 228 and 314 respectively. (Just as a point of comparison, the iPod Touch 8 GB ranks at 245.)

On PriceGrabber, the N800 and N810 are # 2 and # 4 respectively in popularity in the "PDAs" category.

None of this shows actual sales numbers, but the rankings do appear to indicate that Nokia is moving a fair number of units.
