Why is Boxee so exciting for you? Is it simply the online media capability? What does it offer (aside from that) over XBMC?

My last use of Boxee was very disappointing and not something I want to spend time sampling again just to see if it got better. However, I don't care about online media so much and everything I want to watch I have locally. Sure, it's only 250 bucks (or whatever) but if it's underpowered, well, you got what you paid for, right?
