Well, I have no desire to have a web browser on my tv and I really don't have much desire for many apps either. Sure Netflix is cool, also Pandora would be cool, maybe I'd use hulu sometimes. But news stations, weather feeds, stock tickers, twitter, facebook....come on, I have several other more useable devices that already do this stuff. I didn't buy a 46in LED tv to stream everything and view apps that are already on my phone that's right there in my pocket with a more useable interface. I'm not even that into watching YouTube on my tv.
I also don't spend that much time in front of my tv anyways and between netflix rips streaming from my iMac, netflix streaming, and the occasional iTunes purchased video, my tv time is full enough.
It's a cool idea and I'm happy for the people that want it, but for me appletv provides plenty of entertainment, it's simple to use, and cheap. And I'm sure it will have more apps that I won't use soon enough anyways.
