Not sure exactly when I bought the AppleTV, I think it was about 18 months ago. I realized I never wrote a review of how well it worked.
Well, you still aren't going to get it. In the 18 months I have had it installed; I have only used it to watch movie rental 'previews' about 5 times. There's never anything good on it. I did actually rent a movie on it once but it deleted before I ever got a chance to see it. In the same time period I would guess that we have rented 50 to 100 or so movies and TV shows from Amazon Unboxed and watched them on our Tivo's. I think one of the big problems was that we watch the Tivo all the time, so it's right there in front of us. Using the AppleTV requires the "TV input" cycle through which puts a barrier in front of it. Also, we transfer a lot of shows between the Tivo's on all three levels of our house. Only one AppleTV so can't do that (not even sure it can transfer).
AppleTV never found its way into our world..
