When I bought my MacMini as my first attempt to get a "Media Center" in my living room I was quite disappointed about Frontrow: (too) simple navigation, no internet video streams other than movie trailers etc...

Looking at various alternatives like Media Central and now Xhub I got to say: Apple is not that bad in a relative sense. Most of the competitors are not beyond alpha-beta releases. Xhub is surprisingly stable for its age but the delta to Frontrow is (right now) rather minor. RSS Feeds and a build in Webbrowser are a nice and innovative idea but thats about it - the usual simple setup to watch stored movies from HD or DVD or to listen to iTunes songs. No clever idea how to effectively navigate thru a >1000 songs iTunes collection (There must be more clever ideas than just selecting playlists!)

I will watch the evolution of this program but for now there is no real reason to abandon Frontrow.
