I have an A20-Olinuxino-Micro with a battery, so the device can cleanly shutdown when power is lost. I strongly recommend only buying devices that are compatible with Debian main, or mainline Linux at least. Usually I just check if it's compatible with Debian main, and if it's not, I move on. The latest shiney SoC is not worth the software pain caused by uncooperative manufacturers.
