Currently, the controller chip for Thunderbolt technology costs about US$20, a lot higher than the US$0.50-0.80 for USB 3.0 controller chips; therefore, most first-tier notebook and motherboard vendors only adopt the technology in their high-end flagship products.
Since consumers also do not yet have much demand for Thunderbolt-related products and the supply chain for the technology is not yet formed, most accessory and PC vendors are conservative about designing products using the technology.
Currently, Thunderbolt is mainly used by Apple's products and the technology is unlikely to have a chance to standardize until 2014 when costs will drop to an acceptable level.
