Here's another little product that's really cool with airport express and iTunes. It's called Salling Clicker and is available for both Windows and Mac. It allows you to use your cell phone as a remote control (using Bluetooth) for your PC/Mac. You can actually browse your iTunes library from your phone. It is much better than any of the standalone iTunes remotes like iClick. You can evaluate for free but purchasing costs $23.95, which I think is worth it.
