I dont buy it.
- Apple doesnt have "exclusivity" on Thunderbolt or Lightpeak. Windows sides just dont care enough to put it on (yet?).

Intel details Thunderbolt, says Apple has full year head start

At a press conference earlier this morning, Intel offered additional information about its new Thunderbolt interconnect technology being pioneered by Apple in its latest batch of MacBook Pros, noting Apple will have a year long head start in deploying the technology.
As described in the First Look, the new specification pairs PCI Express with DisplayPort signaling in a collaboration with Apple. The PCI Express protocol was used because it's flexible and widely compatible with various types of I/O devices.
"You can extend the backbone of your computer to distributed devices that are connected to it," Intel representatives said, "and to the OS it looks like they're connected to the computer."
Based on work to develop an ultrafast new optical port originally named Light Peak, Intel's efforts to make the new low latency ("8 nanosecond accuracy time sync across 7 devices" for very little delay between operations), low overhead (hits much closer to the theoretical max than previous port specifications because of less background chat), high speed signaling standard was initially held back by the higher cost of optical cabling.
To reduce the cost, Intel collaborated with Apple to pair the technology with DisplayPort to deliver a single copper connection that was high performance and yet still economical.
By pairing the new interconnect with Mini DisplayPort (which Apple developed but has openly released as part of the DisplayPort specification), Thunderbolt should also help drive adoption of the Mini DisplayPort connector as well, which so far has largely been limited to Apple's own equipment. Other DisplayPort monitors from companies like Dell use a "full sized" connector that looks similar to USB, but which serves no value other than being larger.
The new standard is not backwardly compatible with USB 3.0, and Thunderbolt ports can't be added to existing PCs via an expansion card; Intel says the only way to have it is to buy a system or logic board that incorporates the new Thunderbolt controller chip. That's because the Thunderbolt chip needs direct access to both the system's video and PCI Express architecture.
PC makers are expected to begin adding Thunderbolt to their machines next spring, giving Apple a year to trailblaze the technology among high end users before it trickles down into the mainstream. Apple has partnered with Intel in the past to debut its new CPUs on Macs for a brief period, while the debut of DisplayPort (which is not an Intel standard) took a longer period to roll out.
PC makers and Microsoft were both slow to provide initial, enthusiastic support for USB, leaving it to Apple to kick-start widespread adoption. They rolled out USB 2.0 faster than Apple, and many now support USB 3.0 and eSATA, neither of which Apple has included on its machines.
