I think Nokia made a mistake with the N900. The phone functionality should have been a lot better, people expect a 600 € device with phone functionality to actually work well as a phone. And please stop repeating the "it's not a phone, it's a mobile computer" mantra; the N900 has a phone part, so it IS a phone, too, and should be usable as such. Also, I don't think the device will gain all the missing abilities in future firmware updates, development efforts are probably already directed at Harmattan and the next Maemo device.
