Chargers would be replaced with a ubiquitous USB 3.0 solution, supporting up to 100 watts of draw

Today, other than Apple, Inc.'s (AAPL) iPhone, smartphones have made the leap from proprietary connectors to a single ubiquitous standard -- micro-USB.  This is a huge relief for phone users, as it means whether you have a Windows Phone or an Android phone, it's easy to find replacement chargers.

But the situation in the world of laptops remains far worse.

Virtually every manufacturer has its own proprietary brand of A/C adaptors, most of which use some kind of post-style plug.  

But the USB 3.0 Promoter Group has published a new standard [PDF], which proposes using new USB 3.0 power cables as a ubiquitous replacement to proprietary adaptors.  Under the proposal, laptops could draw up to 100 watts off of bi-directional, backwards compatible USB 3.0 cables.  

The USB cable could be plugged into a "mains adaptor" -- an adaptor that converts household alternating current to a useable direct current supply fed into the USB.  Currently, such adaptors are commonly used to charge smartphones.  As the connector to the device -- a USB cable -- is common and the amount of power delivered predictably defined by the USB standard, the choice of current adaptor is inconsequential.

This will make replacing power supplies much easier -- if it’s adopted.

The USB 3.0 Promoter Group is the group responsible for successfully developing and pushing the third-generation USB standard on the world.  Its members include Microsoft Corp. (MSFT), Hewlett-Packard Comp. (HPQ), Intel Corp. (INTC), Texas Instruments, Inc. (TXN), Renesas Electronics Corp. (TYO:6723), and ST-Ericsson -- a joint venture between NXP Semi. NV (NXPI) and STMicroelectronics N.V. (EPA:STM).

Still, even with past successes and a super-star ensemble of industry power players there's cause for skepticism, given the long history of fruitless efforts to move laptops away from proprietary adaptors, as commemorated in the well-known XKCD comic "Standards".  Let's hope this effort bears more fruit that those past failed bids.

Couldn't they fix the USB standard first.. if there was some symmetry in the design then it would be impossible to trying to plugin the cable upside down... what I meant to say is that if the USB connector was properly designed there would be no upside down.. but just to plug it in ^^
