I want a dedicated "mini" PC for using Media Center. I like the interface and the built in DVR is really what I'm after for the over the air stuff. Most of Jen's shows that she watches are network and the ability to record them like we do now is key. Besides if I were to stream everything that is watched with 4 different TV users in my house I bet Comcast would get very angry Also, want a dedicated PC for "ease of use". After all Jen and the kids need to be able to use the TV when I'm not around and I think media center with a HTPC remote would probably be the easiest system to learn. I like the idea of just chromcast from a tablet but really there isn't enough support for chromecast out there yet. That will probably change shortly and when it does I like the chromecast idea for extra TV's in the house.

It looks like I can build a very capable HTPC for around $300. I'm sure that will change though as I'm sure I will get carried away and put extra shit in it that I don't need.
