Oh joy, they still use that damn diving board design on the device side. I've broken 3 devices when that diving board breaks.

Really? How aggressively are you plugging in your USB cables?

I have the same problem. One faulty or aggressive plug angle, and you break some pins or the inner paddle cracks.

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)

100W @ 20V (5 Amps Max)- There are a few uses I would be interested in if it supported higher amperage, robotics is one.

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…

The outer part is the RF shield. That increases reliability by protecting the low voltage (but high frequency) USB data signals from coupling to outside interference (50/60 hz stray emf from power lines, switching power supply noise, etc). The magsafe connectors are just pulling power so don't really need that level of shielding.

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.

It'd be cool with a laptop, but it'll require an extra 20 watts (typical for a ~22" screen) to be sized into the laptop's power brick. Since laptops have pretty predictable power characteristics, the manufacturers don't necessarily give you that much extra.

Would we upsize everybody's power cord on the off chance that 1% of people would use it? Or does "bigger power brick" become another configurable option, and users have to decide in advance if they'll want display powering capabilities? Neither one's a good option, in my opinion.

More likely we'd end up with a separate class of monitor, something limited in size and with a lower maximum power draw. At which point I'd rather just deal with the power cord and get a real screen for my desk. But frequent travelers who want an accessory screen would love it.

This will be interesting, and its needed to keep up with the evolving use of USB. The downside is that once this is everywhere you will be keeping a drawer full of USB adapters (kind of like those USB/PS2 keyboard adapters that are everywhere, or DVI/VGA)

But what about the Lightning connectors on iPads and iPhones? They don't have that outside shield but they carry high speed signals.

I think what will be more likely is the other direction. The monitor powers the laptop. Most laptops are well under a hundred watts and could easily be charged and powered that way.

You've got it backwards... powering your laptop from the monitor is the killer app, meaning an end to proprietary laptop power supplies.

No cord is the future. At least Intel want to get rid of all cables with skylake platform.
