I really like what I've heard so far, but there are a couple reasons that will probably steer me in another direction.
One is timing, as before summer I want to replace my cable co DVR and current PC with a single low heat PC that can exceed the capabilities of both so I don't have to listen to my air conditioning run so often. This is, however, personal, and I understand the choice to ship late this year.
The other reason is cost. While it certainly won't be as sleek or fancy (voice command remote?), I can build something similar to the Delta for a fair bit less, and I can do it in phases as my funds allow. My suggestion here would be to make a free upgrade to Windows 8 available by a certain date, as I'm certain you can obtain the licenses cheaper than us home/hobby builders. Something similar for Jelly Bean on your android emulator would be a nice bonus as well.
