Apple recently introduced a new connection technology dubbed "Thunderbolt." In Apple's MacBook Pro refresh, the Thunderbolt port has been added as a new wired connection architecture that Apple hopes will unify its connection technologies.
The key feature for the Thunderbolt architecture is speed. Thunderbolt promises to be lighting fast (pardon the pun) and offer incredible speeds for data transfers. The need for Thunderbolt is evident for the desktop, but it's not a stretch to imagine that Thunderbolt could eventually make its way to iOS devices.
