MojoKid writes "Promise Technology recently launched the first Thunderbolt-compatible devices; the company's Pegasus RAID R4 and R6 storage solutions can now be ordered from the Apple Store. There's a catch, however. In order to use either storage array, one must first purchase a cable directly from Apple. The company has priced the two-meter cable at $50. As it turns out, Thunderbolt uses what's called an active cable. Inside the cable there's a pair of Gunnum GN2033 transceivers. The GN2033 is a tiny, low power transceiver chip designed to be placed inside the connectors at either end of a Thunderbolt cable, enabling dual bidirectional 10Gb/s concurrent links over narrow-gauge copper wires. The cable's $50 price may be justified, but it's also a further reminder of why Thunderbolt may follow FireWire's path into obsolescence. Apple is the only company currently selling Thunderbolt cables."
That's the thing about people who think they hate computers. What they
really hate is lousy programmers.
