Really works great for most of us who do not need to watch 6 TV's at one time. The 722 in my living room feeds a 2nd beedroom that they can watch at night. Also great for starting to watch a show, pause it and then continue it when you get to bed. I have a 612 in my bedroom that feeds the kitchen TV also since I am not in the kitchen the same time I am in the bedroom. Why would I want to have 4 boxes and pay 4 lease fees when I only need 2? It really does work for many people. FYI if I needed HD on all 4 TV's then I would have gone with 4 612's. Well actually in the kitchen likely not a DVR anyway.
