Picked one of these up for 20$ off amazon. So far its been great to use with anything I have side loaded. My only complaint is I havent found a way to close an app. If I alt+tab it will bring up my usual place to close apps but i cant hit down to close them. Is there a keyboard shortcut or anything like that to close an app when I'm done?
That keyboard has a back key (F1). Another way to exit most apps is by pressing the escape key once or twice. The home key (F2) is a way out of apps which don't respond to the escape key. If by closing apps you mean clearing them from memory, you can long-press the home key and clear them from the recent apps screen.
