@ Pingwhen?
"its just a good idea, not something worth a patent" - You really don't understand the patent system, do you? A patent is the protection for a good idea that someone else would want to copy. It's perfectly OK for Apple to patent this connector. It's not just a good idea, it's a great idea.
It doesn't matter whether it's a good or a great idea; ideas cannot be patented. But an idea would be me saying "wouldn't it be great if there was a power plug that is attached to a laptop in such a way that it is firmly attached and doesn't fall off, but will get attached when a force is used that would be strong enough to pull the laptop off a table or chair and damage it". That is an idea and cannot be patented.
But Apple didn't patent an idea; they actually implemented it in a rather good (not perfect) way, and that implementation is what is being patented. So any laptop maker is free to use the _idea_ and create a plug that saves laptops from being thrown on the floor when a user doesn't watch out and falls over the power cable; but they can't use Apple's way of doing it.
