To hold it was fairly light.
Possibly lighter than my old RC5200. But that's subjective and I had been carrying a 6lb camera around the show all day. (No, I didn't take a picture - I was too tired by then.)

I think you *could* press the hard buttons below the screen with one hand; but two hands would be easier. Mainly because this would involve swinging your hand around to the bottom of the unit instead of the middle.

It's a shame the screen really isn't bluer. All the "really blue" screens I have seen (like my Nokia 8890 phone) put out about twice as much light as green. I think this is because they are really putting out blue AND green, giving more of a CYAN color. Make sense?
