I personally leave mine on/asleep all the time. It has a very long standby time, so you won't see much battery usage when the device is asleep.

I would leave it on and put it to sleep, not powered off. However, it is recommended that you let 'reboot' every so often, maybe once a week, just like you would with a computer.
