Being a well written article about this odd creation from Intel i feel obliged to comment on this:
Note that we deliberately didn’t include Nvidia ION2. Being a very expensive solution with pretty high power needs it failed to become popular, so the mainboards based on it have almost vanished from the market by now.
I respectful disagree about the fact that the ION2 is power hungry and expensive. Granted it costs a few more bucks than E-350 motherboards but vdpau is much better supported than vaapi and both technologies use about the same amount of power. The D525/ION combo is still a viable option in 2012, and at least in my country they are in stock at every retailer. ARM is not an option for a home built media center and probably never will be. I have two D525/ION machines and i am quite happy with them.
