Just bought the $US10 upgrade for my iPod Touch (clearly worth it considering how much everyone else charges for upgrades, revisions, etc). The key feature is now the ability to run applications. I downloaded the Apple Remote - FREE. My Powerbook, running iTunes, streams music via WiFi to my airport express which is connected to my BS3200 (Aux port). I also have another AE connected to my BS1 in my bedroom. Here the fun starts - I can us the Remote on the Touch to control the iTunes on the powerbook - scroll through playlist, pick songs, art, etc. I can selected the speakers - computer, BS3200, BS1, all, none - on the fly. did I mention it was FREE (well, after the upgrade).......... -michael
