Don't forget:

That book is so cool!
It's so genius that it only draws power when turning pages. I mean, that's excactly what we need with these things. Sony apparently claims 10,000 pages, even with a third of that, I think it will be plenty for my uses.
And they even gave it a proper screen definition.
I'm afraid I'm gonna be one of the first to suffer from any first revision bugs.
