Wasn't the original idea of light peak to be optical? Why didn't they deliver on that promise, I want my future back, it's frickin 2011 now and we still don't use optical connectors to connect our devices :)

(I guess they'll have a hard time with the 'Thunderbolt' icon when they go to optical, it makes even less sense for optical than for a low-voltage connector)

Because optical is expensive, less flexible, does not provide enough power for devices (think portable HDD) and not many people use long cable.

Once the technology is widely used, the name doesn't matter anymore I guess.
