I now have two Apple computers with Thurderbolt output, and I bought a couple of Seagate Thunderbolt adapters for 2.5" drives. Looking for a REASONABLY priced Thunderbolt cable, I find none. None. I would have thought there would be a Chinese knockoff by now. Is there a patent issue that prevents anyone other then Apple making these without a patent license ? If that is the case, we might never see these cables at reasonable prices. Discouraging. I can buy a 500GB drive almost as cheap as I can buy the d..... cable.
