Yes, different devices differ greatly in their "sleep" power characteristics. The Sony PRS-600 drains its battery in about a week if you don't use it. The BeBook Mini does seem to have one of the better power-management systems, but at the expense (so I've read), of sometimes missing button presses due to not "waking up" quickly enough.
