I believe it's going to be some time before we see USB Type-A assigned to the dustbin of technological history. Think of VGA and DVI, which are still around, and while more devices are making full use of USB Type-C, and I'd be more than happy to see the entire connector replaced overnight, it's just not going to happen with the sheer number of consumers who still rely on USB Type-A cabling. Laptops are leading the way, with some only sporting the smaller USB ports, while desktop PC motherboard vendors are slowly making progress.
