I'm going to call DirectTV and cancel our service this week. I've managed to replace our TV program with the usual suspects (netflix/hulu/etc/. The problem is I've done all of my experimentation using my MBA and I don't really want the family to need my personal computer to watch television. What is the least expensive, most reliable device to manage streaming content to our TV? Current setup is MBA and ATV so I'm guessing either an iPad or a low end Macbook of some kind - maybe not the latest? I do have an iPhone 4s in a drawer - should I consider that? TIA.
