Interesting timing giving the Docker funding news.

How is this different/better from Apple's connector?

It won't be patented by Apple. Which is a hindrance to a 'universal' connector design. Of course Apple started patenting its connectors in part to give it a weapon against inferior cable/accessory makers (or so I'm told).

Occam's Razor: Apple patented it in order to own the invention.

I think the iPod / iPhone chargers that caused fires was a concern.

If a company isn't worried about fallout from negligently designed mains equipment, they certainly aren't worried about patent lawlers.

If I remember right, and it started with golf clubs of all things, patents give you a way to stop the import of these items. I figure Apple patents everything anyway.

Perhaps offering a host connector specification, more speed, higher power capability, industry standardization, non-proprietary implementation, and lower cost are some advantages.

I'm sure it'll be very different. Probably not better, except that it'll be open.

As open as USB is. There have been a few articles on HN showing what the limits of that is.

It'll be on non-apple devices.
