Hmm. That's right on the edge of what I'd consider good enough. Damn, hoping for a definate answer one way or the other

I'm confused on the point of USB charging. You want to charge your book reader with a laptop, but a laptop battery typically last ~3 hours (less when charging something). How do you charge the laptop?
Maybe it's because I always have access to a power outlet when traveling, but I never saw USB charging as all that useful for anything.

Two reasons.
First, as HarryT said, to reduce the number of specialised power cords to hump around. Pretty much everything new nowadays can be charged from a standard A->B USB cable. iPod, Palm, BlackBerry, GPS, even a PSP with a different cable, all can be charged from the laptop.
Secondly, for transatlantic flights and hanging around in airtports. I've got a fully charged laptop in my bag that isn't doing anything useful, but I can use it as an extremely expensive external battery to extend the life of the devices I'm actually using. I'm carrying it anyway, so why not get some use out of it?
Is the power adapter universal voltage, btw? The iliadreader page doesn't say one way or the other.
