Sorry, I think we're just talking about different aspects of the UI. When you say "so far everyone else sees fit to ship next to unusable interfaces," I take that to mean the actual method with which you navigate around the interface. I wouldn't say that Apple's wasn't more attractive than most of the boxes out there (it is), but overall Boxee is FAR more attractive than Apple's very plain, boring UI.
And I stand behind my statement that the actual navigation is no different than half of the other boxes. You select your activity on one axis, then drill down into that activity on the other to pick what you want to do. In fact, after that, it's really not that different from the iPod media player from a navigation standpoint, which I thought you hated.
One point I definitely won't argue on is that Apple made the best slideshow device I've ever used. I love how it displays photos, although the "Ken Burns Effect" occasionally cuts off people's heads

I'm not kidding when I say my #1 favorite thing about the AppleTV is the screensaver. My dad and I used to sit there listening to music and watching the photos scroll by. It was so fun to pick out photos to comment on. Fantastic.
It's funny. For the longest time, the UI clearly emphasized Apple's content over your personal collection. The very first item in all the top-level menus was always for iTunes store content (browsing movies and music to purchase). But recently with the last update, I think they actually made your own content the top item. Now this new box is clearly focused on Apple's content again. Oh well.
