Sumitomo Electric's Thunderbolt Cable
 

Since the launch of Thunderbolt the only cable supplier has been Apple. Given that no current Thunderbolt devices come with a Thunderbolt cable (save Apple's own Thunderbolt Display which comes with one for video input), anyone who wanted to use Thunderbolt had to pick up a cable at the Apple store for $50. Sumitomo Electric started shipping its Thunderbolt cables at the end of last year and Intel had a pair at CES this week. They are functionally identical to Apple's cable but come in a dark grey instead of white. No word on pricing unfortunately, although I do know that there's a definite push to drive the cable cost down this year.
