Thunderbolt is Intel's external, hotswappable PCI-e interface found on many Apple laptops. Lightning is Apple's proprietary interface found on iOS devices. Aside from being named after different aspects of the same natural phenomenon, they have nothing in common.

Not sure how I got those so thoroughly mixed up, thanks for the clarification.

Well, being named after the same natural phenomenon is confusing enough. I often have to stop and think which is which. It's an understandable mistake.

Thunderbolt and lightning? Very very frightening.
