As much as I'm looking forward to this other advances have made it seem less important. Many of my things that used to be usb are now wireless and I no longer have a bunch of usb hard drives attached to my machine since I started storing / backing things up to onedrive. Even small flash drives aren't used as much anymore. I used to have to often sneaker-net log files etc from one system to another but now I just have them sent to a shared onedrive folder.
Having one cable to connect a bunch of things will be nice though. Bring on the progress, I say!
