Sounds great! For anyone not sure of the context, right now Type-A is the "host" end and type-B is the "device" end. However since OTG was introduced that correlation isn't concreted and can reverse during the connection. I might have misunderstood but it sounds like Type-C will be a symmetrical affair (the cable will be reversible). I guess this opens the door for totally new use cases for USB? With extensions to the OTG system we could be connecting two hosts for e.g. transferring files between laptops. Again I could be wrong about that.

Also 100W power is great - The power delivery capability of current USB is really limiting.

And reversible cable orientation? We are entering a glorious new era.
