I have done research on this topic, it is a standard, not ratisfied yet, and no way your old usb cables can take 100watt power(voltage/amperage), also wall sockets need standards, which is not there yet. there are other working powered USB implementations available http://en.wikipedia.org/wiki/Powered_USB

The example you cited doesn't even use the same connector. Furthermore, the support of Intel and Microsoft is basically a sure-shot that we'll see an implementation. There's skepticism, and then there's just silliness.

Expect a new class of cheap USB gadgets in the future. USB powered microwave oven. There's a lot of toasty cheese melting power in 20 volts and 5 amps. There's going to be some patents filed...

I'd be careful with these; it means you can't plug in an untrusted power supply anymore.

Just imagine one of these cables also acting as a USB keyboard, which brings up a new terminal, adds an SSH authorized key and closes the terminal window without you even seeing it.

This is awesome, being able to charge everything from a single power plug is a total dream. But it'd mean losing MagSafe and I can't see Apple going down that route.

Just use an adapter, apple customers seems to love those.

Er, Apple designers seem to love those.

How often are you currently plugging in untrusted power supplies? ThunderBolt can chain a lot of different device types but I don't think it's a huge attack vector to plug in untrusted monitors.

20v@5a! Nice! I can't wait to see USB ports instead of the 13.8v ports we currently have in cars. Sadly my 170w laptop still would need a separate adapter.

A decent number of cars have USB ports (usually for audio purposes but they also supply power). Ford Sync comes to mind here.

Stockholders should too.
