Bluetooth for everything

Isn't it a little late in the game to come up with this concept...like 10 years too late...? Connecting home devices via Bluetooth sounds like a great idea in theory, but technically speaking, is it really possible to get good video streams to portable devices...say...10-15 feet from the transmitter? Why did it take almost 10 years for the technology to mature into this...? The only good function I can truly see out of Bluetooth at home is being able to control device functions from a distance, maybe...handling phone conversations, as long as you stay close to the transceiver (10 -15 feet at most).
