I'd like to see an interim conversion adopted for charging from USB3.1 to things like Magsafe on the MacBooks. In the dark days of laptops, stepping on the power cable could end your laptop, USB 3.1 looks like it'd be a return to that if used as a primary charging source.
Other than that, USB3.1 looks fantastic. Thunderbolt 1.0 speeds, big power, and much better connector.
