The functionality of this Android Mini PC is already gigantic. By Android and the preinstalled Play Store can be pretty much all the apps you want to install. Whether Youtube, Facebook, Spotify, Skype and of course XBMC. The latter is an ingenious media center for your film collection for all who do not know it. Movie Cover, Trailer etc. everything is possible. In the system you are quickly on your way. You can also install another launcher, for example, the well-known Nova Launcher. The remote is the only downer. But since I still have a Logitech K400, no problem for me (app External Keyboard Helper additionally for the DE layout install).
The two versions: one with 8GB and 2.4GHz WLAN and the other version is exactly the same up to 16GB and 2.4 / 5.0 GHz WLAN.
