Well, I still have the Boxee Box and the Roku. I received a delay in shipment email on the Dell Zino and opted to cancel the order altogether. I'm going to try to upgrade some parts on my current desktop and turn it into a media server (I don't have any HDMI ports on it).
I've also come to the conclusion that I will not be able to ditch DirecTV at this time. I can't find an antenna solution for OTA HDTV that works in my condo (at least not at a price I'm willing to pay). I was able to get a $10 per month for discount for a year from DTV because I asked based on being a long time customer.
