I am sorry to agree that the camera is absolutly useless, as the cameras in all but the best mobile phones. It's just a way for the brands to increase the apparent value for money without increasing production costs.
If the quality was even close to usable, the camera would be a nice addition, but that would cost money. That is why even the cheapest phones have a camera - people wouldn't buy them if they didn't have one because they would cost the same, but nobody ever uses the camera.
It does not add to the cost, so we shouldn't complain, but it actually makes the device (N800) bigger.
Anyway, wasn't this talk about the FM radio?
Any news regarding that?
