AirPlay and AirPlay Mirroring add a lot of value to the second and third generation Apple TVs. Paired with a recent iPad or the iPhone 4S, an Apple TV can instantly become a gaming solution and a theater for home movies – and will be amazing when combined with Mountain Lion when it ships this summer.
AirPlay also turns that Apple TV into powerful and extremely portable presentation system that’s a great fit for the classroom or the board room. The only challenge is that the Apple TV’s only output option is an HDMI port, which can be a big problem for connecting to older display technologies including many projectors and computer displays – a problem solved by cable and adapter maker Kanex.
