There Oughta Be a Standard: Laptop Power Supplies 482
Esther Schindler writes "Every mobile device you own has its own power supply and its own proprietary plug. There oughta be a better way, says Alfred Poor. Fortunately, he reports, the IEEE is coming to the rescue. "Their Universal Power Adapter for Mobile Devices (UPAMD) Working Group is developing a new standard that will not just address the needs of laptops and tablets, but will be intended to work with just about any electronics device that required between 10 and 240 watts of power," Poor writes. It's about darned time." If there's one thing I wish for all laptop power supplies, it's that they would license from Apple (or work around, patent-wise) the magnet attachment system that makes cable-tripping far less dangerous to man or beast, compared to a few years ago.

I could imagine that efficiency will improve. Right now, a laptop manufacturer that includes their own power brick has not much incentive to make it really efficient. It's easier just to make a bigger one with a cheaper design.
With a standard connector, there will be 3rd party vendors that offer standard bricks, and some vendors will aim for the highest efficiency as a selling point.
