And one more thing for folks who, as I was, intrigued by the concept of Apple TV but reluctant to shell out the dough: I soon realized I already owned all the tools necessary to jury-rig my own crude but effective version of Apple TV. With the help of a $20 video adapter I plugged my MacBook into my A/V receiver in my living room. The MacBook connected to my wireless network automatically and was able to stream content not only from my PowerMac G4 tower upstairs, but also from a networked hard drive. I even was able to use Front Row to access the G4's music and photos, though the video refused to play. However, using iTunes to access the G4's video files directly via the Shared Library feature, I launched the series finale of Stargate SG-1 and watched the whole episode with nary a hiccup. And my MacBook uses the 802.11g wireless protocol, not the newer, faster 802.11n standard built into Apple TV.
