I'm not an apple fanboy - but I do really like their magsafe & iPad mini connectors (whatever those are called officially). One thing I really like is the lack of "sticky-out-bit" in the middle of the connector, which all USB sockets seem to have, and which always feels kind of unstable or weak to me.

Is there a reason why all USB sockets - including these new diagrams - have a feeble looking centre part rather than it being part of the outer ring?

The USB Power Delivery spec is pretty interesting too - up to 100W @ 20V over USB (presumably with modified cabling, too :P) http://www.extremetech.com/computing/172113-usb-power-delive... (a link from a link on this comments page)

Powering an external monitor from a laptop is appealing. One cord to the wall.

Even cooler, would be driving an external monitor from a smartphone.

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.

Came to ask the same thing. Those little pins always break for me.

I worry somewhat about the smartphone's battery in this context. I wonder if any have good 'passthrough' for when the battery is full and a wall socket is connected - even then I doubt it. :/

That will be expensive though. You'll have to pay the medical bills for getting your back fixed after having to carry the suitcase with the batteries :).

Current cell-phones have batteries around 2 Amp-hours. At 5 volts, that's 10 Watt-hours. The least-power hungry display according to [1] is a 15 inch LED; it clocks in at 15 Watts. This means you'd be able to use your external 15 inch display for 40 minutes before completely draining your battery. That is not counting anything the phone is actually doing, just powering the display.
