Well that is all going to change.
The USB Implementers Forum announced they are working on a new plug that will work however you plug it in. Other features will include a smaller size plug and the connector design will scale for future USB bus performance. You can read it all on USB Implementers Forum document.
Smaller Type-C connectors will be an advantage to newer and smaller tablets, phones and notebooks. Alex Peleg, Vice President of platform Engineering at Intel stated his excitement over the device. He believes this will become a great all-in-one plug and the “only connector one will need across all devices.”
Current USB 3.0 standards can transfer at speeds of 5 Gbit/s. As compared to Thunderbolt 1, which can do 10 Gbit/s per channel (20 Gbit/s total).
This new connector could show up as early as mid-2014 when the USB 3.1 specification is expected to be completed.
