Bought a Vizio "Internet" TV last year.. The biggest issue is it really isn't a Internet TV but rather a TV with Internet "APPS" on it.
Vizio even has a nice remote with slide out qwerty keyboard but still pain in the rear trying to vavigate and type in anything
Mostly use it for Netflick
One other thing I notice is that when I am done working on the Computer ..I go to the TV to Relax and watch instead of wanting to participate with the TV.
could be because I am getting to be an old fart ;)
