I agree with Texaport on this one.

I own both an ATV 2 and Roku xd. The Roku is great for older tvs because of the Rca capability, but as far as cleanliness and overall feel, ATV is better.

I also have a thunderbolt connection to a flat screen display that i use from time to time, just to play a few games on, but its just not as easy as just having something always hooked up.
