What is the Apple TV?
The Apple TV is a sleek attractive device that fits into your living room entertainment center. The Apple TV is a simple five minute setup and impresses everybody who tries it with its elegant setup, beautiful usability and (for the geeks) huge expandability.
I highly recommend purchasing an Apple TV if you already have a standard or high definition TV that has component inputs and widescreen display, after a simple setup where you'll pair one of your computers with the Apple TV, the Apple TV will synchronize its built in 40Gb hard drive with the iTunes library on the host computer.
The Apple TV can also stream Music, Videos and Pictures from five other computers throughout your network and it does this all smoothly using the ubiquitous 802.11G wireless or it's latest generation 802.11n wifi.
The Apple TV is available for purchase from Amazon
