I'm not sure if the way you use the trackpad is well thought-out. He mentions you need to "roll" the finger up and down to scroll up and down, "just like on an ipod". Which is not true, since on the iPod you actually swipe your finger along the wheel ... this trackpad looks to me like it's better suited for swiping than press-rolling.
But a nicely designed device, I must say. Gets awfully close to all those futuristic ebook designs, I think it's the best-looking device.
I wonder if it's "porshah-designed"
