I spent a few minutes last week playing with one of these units and it seems like THIS is what the future of home entertainment is all about.
It's a step shy of a fully blown media center PC, without any of the issues related to a HTPC. No configuration crud, and all the outputs and connectivity you expect from a home theater product including HDMI and component video HD otuputs.
Now, I didn't spend enough time with it to really understand it, but it sure seems like it is right on track for what people want.
Video playback? Check!
Music playback? Check!
Photo browsing? Check!
Easy control (I think it's a 5 button (or so) remote) - Check!
It does a bunch more in there I think, but it really does seem to be what the home theater PC often fails to be. A basic interface between the PCs in your home and your nice home theater setup. With a price of.. what is it? $250 or so? Not exactly going to kill many of us.
I really wanted a good interface to play my 'home movies' from the hard drive on and this may be the ticket!
