That screen is about the Sony's size, rotated.
I like the touch strips, it would allow reading from any position. That is good ergonomics. There is a drawback to it though. If its too sensitive, one will have a tendancy to wreak havoc in one's reading linearity by inadvertantly touching strips at the wrong time and place.
That would make it
hand under manipulation only.
Of course at this point in time the display
should be colo(u)r!!!
The only drawback for me is it being HP. They're specialists at outdating their wares too quickly.
And what about their software being separate from the hardware? They usually get out of situations by blaming one against the other!
