I'd like to buy a Mini to connect to my TV to stream Hulu, etc. Which version of the Mini should I purchase? Do I need the 2.26 or 2.53 Ghz version, or one of the older versions from Ebay work just as well? Hard drive space is not really a concern of mine. Any help is very appreciated. I'm going to sell my Apple TV on Ebay - that thing blows.
