That suggests it's using more power than the screen.

Amazon's suggestion that people leave the wifi on so they can receive OS updates is nuts in my opinion. I don't know anyone who does it, though perhaps people who are used to plugging everything they own in to recharge every night are happy to leave the wifi on 24/7.
I get the Wall Street Journal and the Financial Times delivered via WIFI.
Plus, I like my books and notes to sync.
So I don't ever turn it off.
