I agree on most parts. However, I disagree with:
How do you figure? To me, it's in the most logical position as is. The switch you're suggesting wouldn't really make a difference when in phone mode anyway, but it would make the volume rocker awkward to use in landscape mode. Hence why the current position is more logical to me. The only difference I see for phone mode is that if you hold the phone to your left ear you can change volume with your thumb instead of your index finger (and vice versa if you hold it to your right). But it makes no sense to move the button for that - both index finger and thumb work equally well for me, and there's no way to know which ear people will use the phone with anyway. In fact, I regularly swap which ear I use while I speak.

I'm equally surprised. It seems like it would be very awkward, regardless of how flat the backside is. But to each his own, I guess.

Finally, I have an additional suggestion to Nokia:
14) Move both the usb-jack and headphone-jack further up, in relation to lanscape mode. Presently, the cables are a bit annoying when using the keyboard.
