I know quite a few people who have a blackberry for work and opted for an iphone for their personal communications. Also, most of the people I know who had Treos have moved on to iphones. On coder blogs (not maemo) I occasionally see people talking about their iphones. Because of the larger installed base for iphones, I suspect that their are more developers with iphones than there are with maemo devices. I think these people know how to be productive and weren't looking for a fashionably unproductive device. The iphone met their needs -- even with its myriad of deficiencies. If the maemo phones are significantly more productive devices, some of these users will jump -- but I don't expect Apple to sit still either. I personally don't want an iphone. But on the other hand, I have seen no NITs in the wild other than mine, but I see lots of people getting iphones -- admittedly many from people just moving up to a smartphone.
