No, I didn't. I don't use Pis, I have ODroids. Heck, they may sell batteries for ODroids, too.

For me, it wouldn't have made much difference because I have UPSes around the house serving things like routers, modems, and switches. And I do care about size and energy use. I'm only saying there are advantages to using laptops.

You can get little integrated LCD cases for Pis too, can't you? And maybe even a little fold-out keyboard. Congratulations! You've re-invented the laptop!
