I found it quite buggy. When I attempted to load a slide show from the photo menu my Mini completely crashed and rebooted on its own! Now THATS a crash for a Mac. I'm using Amp 1.4 at the moment. Not very intuitive layout but the overall UI is what I was close to what I was looking for. What I want is a Front Row 2 without all the quirks and touchscreen/finger flick scrolling (ala iPhone). I would pay money for that.
Nice setup you have going though. Hopefully once my installation is finalized I will be able to do stuff that efficiently.
