The developed jointly with Apple and Intel Thunderbolt interface has received a limited distribution because of a closed ecosystem, the high cost of controllers and other components, as well as non-obvious advantages compared with the much more popular USB 3.0.
Intel representatives explained that some of the existing bias is not relevant. First, the cost of Thunderbolt controllers are now $ 10.
Second, the slow spread of Thunderbolt is due to Intel desire to carefully monitor and control the quality of products that support this interface. The certification procedure was slow, and in the market is not more than 80 devices that support Thunderbolt. However, this year things will change for the better - for the moment license to work with the interface have about 220 . The turning point came in the fourth quarter last year, when the number of partners to promote Thunderbolt has grown significantly.
