I have even tried to sell my N900 couple of times (without any luck). It's not that N900 isn't amazing gadget, N900 just doesn't have that extra something (personality maybe) that would appeal users feelings.

The alternative would have been Droid (Milestone in Europe). This one has even a name (not in Europe) that suits it looks and design (which is also quaint). N900 has not.

It's not something that is a necessity, especially if one is buying a tool for working and communicating. Then it doesn't make any difference, if you are using Z450 or GLP-6. It would even be a bit silly, if your tool would be called "Cookie".

On the other hand, phone is usually more personal thing, more than just black, cold plastic bar in a grey little room in your office. It goes with you everywhere, people see it with you in public etc. It's a part of you. If the N900 in your life still feels like just a piece of plastic, it just doesn't do everything it could to win your heart. Droid does. =/

E: As a matter of fact, this is one the reasons why competitors have these killer models, IPhone, Droid, Chocolate. They got personality. Or the manufacturers are really trying to make one. Nokia doesn't even try. That makes any Nokia just a phone/tools/mobile computer.
