Not to nit-pick, but much isn't much of the PBS library already available free online? It might be. I can't find Thomas the Tank Engine, Dinosaur Train, or Bob the Builder programs online, but if you know where they are, I'd be indebted :-) Although still having them through a service that is carried by things like Roku boxes is a big plus, since most TV viewing by my familty is still on the TV. Although I'd consider a GoogleTV box if that was the only way.
