I wish I could get my hands on one of those, would be cool to read from a PSP than a book. Why carry around freaking 7-11 kilograms of books with you all around, when you can hook it up to a cord, place it on your neck, get a charger, put it in your pocket and walk with it all day long without the constant back pain (or the neck pain associated to having a laptop backpack). The PSP could be fitted with a proper eBook reader (or a proper interactive educational application), Why limit your self to 3-5 books when you can carry one object and have more than that?
