if someone have not had a smartphone before N900 is probably mindblowing. But after using iPhone since 3G with which I have created movies, music, musicvideos and photoediting stuff there has to be reasons why to start to use N900 as a main phone. N900 does not stop your own brains working the same way as does new smartphones. A bit slower and less capabilities prevents your brains to adapt smartphone as an essential part of your brains. And with N900 you stay smart and become smarter which is vice versa with newer phones.
