I went with the original Apple TV instead of the Wadia iTransport. Think of it as a 160 gb iPod with an optical output. It's far easier to control, is significantly less buggy, and has a lot more functions than the iTransport.
You can pick one up on Amazon for $150 and get a refurbed iPod Touch from the Apple Store to use as a remote for cheaper than the iTransport.
