I just returned my Airport Express and literally stood in the store for an hour debating on the Apple TV vs Mac Mini. I opted for the Apple TV as I really just want a music server at its most basic level - hard disc storage, digital out and a slick user interface. I like that I can sync a library off my PC into the Apple TV and play it back off its internal hard drive.
The Apple TV is a slick multi media device and could not be easier to set up.
