Yes, but how accurate can we assume the information is? The same source claims the iLiad batteries are good for a week at three hours of reading per day. That was part of the original marketing claim by iRex, but linuxdevices.com doesn't appear to be checking those claims very carefully. They are probably right on the main specs, but I'd be hesitant to assume they've got all the details.
That being said, yes, at least they seem to have more than "it's thin and light!"
I still don't think the functionality is worth the price they're quoting, but it's nice to have a little more info.
