At work I got this phone and I've to say it really limits the need to bring along the N810. It has almost everything (and more) I was using in the IT in a third of space and weight: - gps (fast) and maps N810 has even better maps (Maemo Mapper and Wayfinder Map) and works great with ext GPS (the internal GPS of the 5800 is crap and I think the E71 GPS is not better) - qwerty keyboard (smaller, but better) For mouselegs it is better but not for human fingers. I barely use the hardware kb of the N810 as the onscreen is configurable. - wifi and bluetooth N810 as well - putty client N810 has native SSH - fring client N810 has a much better 'internet call' much better than fring on E70 or 5800 - internet browsing with flash (casual use) N810 same and has no WAP user agent (check www.cnn.com or www.smh.com.au these are shown as WAP pages on Nokia phones) - email N810 as well - better PDA If you need PIM you're right otherwise, no.... - PDF reader N810 as well - small office (word, spreadsheet) Yes that is NOT on the N810 - sport-tracking N810 as well lots of such apps - mp3, real, youtube players N810 as well and Youtube just plays natively in browser - microsd card and moreover: - 3G connection With N810 over BT - ah, yes: phone calls
