Web surfing on a TV is pretty thin at this point. The Sony Google TV models are able to do it. My guess is LG will be the first to do 3D and a web browser, but nothing concrete yet.
Edit: The browsing experience on a TV set is very poor at this point. Limited plugins, flash, java compatability, as well as stabiliity and performace issues are really what prevent anyone from doing this. If you have a tablet, laptop, or PC handy, it's a far, far better user experience.
