I fail to see the appeal of internet on the ATV. There are so many more appropriate and easy ways to surf the net...
I see the AppleTV as my iPod/Touch for the TV. If you can do it on the iPod/Touch then it would be nice to do it on the AppleTV. That includes surfing the web. However, for me more video content is most important. Of course that would not require any changes to the ATV itself. Just make more deals with the studios. As far as adding Netflix, why can't they make the same deals and get more content from the studios. They have done pretty well with getting music content.
