Tech Ping!..........
I don’t see some massive step forward on I-TV unless they connected you to some central TV warehouse, and allowed you to watch 10k channels (from Ireland, China, France, etc)....all for $10 a month.
Bandwith is the limiting factor in having high quality interactive television. The new bandwidth gold-standard is 1 gig up and down. Houston and Chattanooga have this kind of bandwidth, but not from the incumbents.
This yields HD quality interactive everything without the network breaking a sweat. What is needed are apps that make use of the bandwidth.
