As much as it irks my libertarian sensibilities, it would be nice if some standard were defined and enforced for this. Seems to be coming to fruition with cell phones and the micro-USB chrage/sync connector the EU seems to have settled on.
The vast majority of laptop parts are very similar, so the power requirements shouldn't vary all that much. Most every Dell laptop I own, or have owned uses about 19v, at various current capabilites. I can see making different connectors for different wattages, just like is done for household current (15A plugs are different than 20/30A ones so you don't plug a dryer into a 15A socket), but why should two laptops whose bricks are both 19v, 3A, have different connectors?
Just got a HP Slate, whose little power brick was identical in spec and even physical size to an HP Mini I had, but the connectors were vastly different, requiring me to buy yet another extra brick for travel and as a hedge against the one dying.
