It makes sense that Thunderbolt debuted on Apple's MacBook Pros. Perhaps more than any other devices, the Apple's MacBook Pros have a high reputation among media creation professionals. And kudos to Apple for having the foresight to launch products with Thunderbolt, even though actual products will clearly lag behind in availability.
For Thunderbolt to take flight, we need to see widespread industry adoption in both business and consumer devices, across both storage peripherals and across systems.
Furthermore, where Thunderbolt's impact may be felt lies down the road, far into the future. Given a few product development cycles, the reality of Thunderbolt is that we may see new models evolve for audio/video production systems or super-speedy local data backup and archiving. Thunderbolt can even aid the transcoding of content, thanks to its compatibility with Intel's Quick Sync Video.
But first we have to get Thunderbolt out there and on devices. And that will take some time to ramp up. Once it does, though, we may all be speeding along--never again grousing about grabbing a cup of Joe while waiting for data to transfer.
