Intel Apple has just updated its line of MacBook Pros. Usually, this isn't anything to get particularly excited about, but this time around, they've got a genuine treat: Thunderbolt. Apple is the first to use this new connection technology, developed at Intel and believed to be the copper version of Lightpeak. It's pretty impressive.

Copper wire is a noisy medium, requiring sophisticated forward error correction to get good throughput. The logical protocol may be PCIe, but the physical signal encoding is probably something proprietary to Intel. Sure, it's probably BCH codes on top of trellis modulation, just like broadcast HDTV and similar to Gigabit Ethernet, but there are probably some Intel tweaks they feel are patentable.
