I didn't mean to imply it's an Apple interface - but I haven't seen TB 2 in the wild anywhere else then MacBooks/iMacs and most Thunderbolt devices refused to work with Windows (at least as I tested on my rMBP) due to lack of drivers. I did not mean to cause confusion, I apologise.

I have been seeing Thunderbolt as an option on motherboards when I do builds for at least the last three years. But I am generally looking at motherboards in the $200 price range, as the lower end ones are usually lacking connectors and features in ways that are much more important to me than Thunderbolt.

Manufacturers I believe don't usually include it because most PC buyers would not use that feature as a purchasing criteria.
