The obvious end game for USB 3.1 type C is replacing your laptop with a phone. USB 3.1 type C is the "universal docking station", providing power, data & display over a single cable. Obviously useful for a laptop, but even more useful to a phone. Apple obviously could merge OSX & iOS into a single OS, but I have real difficulty seeing them doing that. (It also seems unlikely that they'll replace Lightning with USB 3.1 type C). It seems much more likely that Ubuntu, Microsoft and possibly Google are going to go there first. By pushing USB 3.1 type C, Apple really seems to be opening doors for their competitors...
