Although Apple’s September 9th event looks like it will super charge the Apple TV into a PlayStation-killing video game console, it’s not the indisputable king-of-the-hill of streaming media boxes right now. Roku, Fire TV, Chromecast… all have their advantages over the Apple TV except for one killer feature: AirPlay Mirroring, which allows the Apple TV to stream anything running on your iPhone, iPad, or Mac.
Unless you have an Apple TV, you can’t use AirPlay Mirroring… right? Actually, you can, as long you have a Raspberry Pi.
