He compared it to the Panasonic R5, and includes pictures and comments on weight/size. He also mentions using screen protectors, something which many have seemed hesitant to do, because they feel it will either change how well you can write on a Tablet PC/Convertible (even a passive one like the P1620) or how bright the display is (due to another layer being added to the display):
I bought the five-pack of screen protectors. This is the first machine I have ever used a screen protector for. But based on reviews of other touch sensitive displays, I figured it was necessary. I like the feel of writing on the screen protector. I don’t feel like it hurts screen visibility at all.
