"the unprecedented speed of the new Thunderbolt technology places unique demands on the physical transmission media."
Tricks like this to deceive the consumer into thinking these speeds are new irks me slightly. Other than that, as always, new tech quickly depreciates in value. But in this case it won't be because of superior tech, but because your average Joe home user will stick to USB.
2 hours to backup 100 GB to an external drive? You can still use the computer. Or go outside and play soccer.
This tech will be used by professionals only, but that is because its a professional piece of tech. Firmware in the cable? Internet meme ahead!
P.S. Long live the USB!
