Umm...

I don't get why people buy the N900 then go to a N1/iPhone instead then complain about the N900.
It's like going from a 5 seater SUV to a 2 seater sports car then complain that the SUV wasn't as sporty.

N900 has a hardware keyboard. iPhone/Nexus1 does not. This to me is the biggest difference.
There is no way I would buy a phone for myself that doesn't have a hardware qwerty keyboard.

N900 isn't perfect. But you knew that when you bought it. Right?
