Recently on woot.com they had the iGo everywhere15. I like the concept of reducing the amount of stuff I carry so I picked one up. Recently on woot they had an iGo EverywherePower 7500 so I picked up one of those too.

iGo has a slogan on their literature, One adapter for all your devices. They advertise that all you need to do is get the different tips and plug into anything (as long as the adapter has enough power to run it). When I put the two iGo devices together I discovered that the tips have different connectors so I can't plug the ones from the 15 watt unit into the higher watt unit. Heck not even the power cords are the same.

Are the other brands of power adapters this exasperating? Do the Kensington tips fit all of the Kensington units?
