CooCooCachoo.... actually the laptop manufacturers lose more than they gain because many laptop power connectors fail within the warranty period costing companies like HP/Compaq, Dell, Gateway big time.

I am not an Apple fan but I have to hand it to them in the manner they solved the problem. Apple notebooks have a connector that uses a magnet to hold a flat (rectangular) connector against a planar contact surface. If someone trips over the power wire, or the user forgets it is plugged in and carries the notebook away from a desk, the magnet just lets go of the power adapter's wire and there is no harm done. It is a smart solution. I'm sure if you ask Steve Jobs he will say it was his idea :-).

We all live in a yellow submarine.
