Chargers would be replaced with a ubiquitous USB 3.0 solution, supporting up to 100 watts of draw
Today, other than Apple, Inc.'s (
) iPhone, smartphones have made the leap from proprietary connectors to a single ubiquitous standard --
. 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.

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. (
), Hewlett-Packard Comp. (
), Intel Corp. (
), Texas Instruments, Inc. (
), Renesas Electronics Corp. (
), and ST-Ericsson -- a joint venture between NXP Semi. NV (
) and STMicroelectronics N.V. (
Still, even with
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
". Let's hope this effort bears more fruit that those past failed bids.

Because the apple connector isn't a USB port, silly.
They do other things, and the form factor is better. Ever tried a mUSB dock? They are crap compared to Apples. I'm also betting that the new Apple port has thunderbird, another reason.

Thunderbird? And yes its a proprietary USB implantation. If you meant Thunderbolt then your an ... absolutely no benefit having it be thunderbolt, all it would do would raise costs.

Yes, I mean thunderbolt. (DOH!)
While the apple connector includes USB, its not an illegal device and its very much an Apple standard, its not rare.
Go to walmart or any general phone store and count up all the accessories for iOS products and compare them to the others. Guess what, apple has a standard that allowed accessories that cannot be said for anyone else. Samsung moves its USB connector depending on the phone.
And again, plugging in an apple connector smokes USB in terms of ease.
Apple helped develop Thunderbolt. The price for the new Thunderbolt macs didn't go up, neither did the monitors. Thunderbolt for PCs is quite expensive.
Now, I didn't say the new port on iPhone5 (and future iOS products) is thunderbolt. I said/meant it would have thuerbolt included. But it should include USB3.0 as well, or at least have USB3 if there is not Thunderbolt. USB3.0 would be easier to work with. We'll know in a few months.
But I'm betting TB & USB3.
