I think some kind of multimedia store built into TVs can be great as long as maybe TV shows are free and everything else isn't overpriced...

With built in HDDs for such a service (unless it's all streaming, but that would suck for many) they can also build TVs with a DVR system, so if you don't use the space for the store you can use it for recording. Maybe they could charge for that too, like buying a program. Sucks for us but if they can profit off of something it's bound to be included...
