Intel's deal with Yahoo! is the harbinger of the web connected TV (as opposed to the TV connected PC). More and more screens arrive with internet connectivity, but the lack of a processor means that functionality is limited and slow. Now applications such as Inuk's virtual STB technologies as well as browsers and Flash can be integrated with the screen.
As I've recently blogged, this is likely to have a profound effect on how people treat the TV and will open up new possibilities, especially for eCommerce.
