Thunderbolt isn't an Apple interface, it is an Intel interface. They were the first to use it, because they picked the best and fastest interface to combine video with network, USB, firewire, etc into one cable. However, several other brands have caught on, including the Dell m3800 I bought recently.

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.
