Seriously if I'm buying a laptop one day and I'm finding out that there's no power cable in the box, I just bring it back and said that they made a mistake and forgot something.
They are just trying to press any last dollar from their customers, that's it.
When you were buying an iPod a couple of years ago you had the AC adapter, USB/FireWire cable (and long ones!), sometime some extra accessories (pocket holder for the iPod Mini). All those small extras were really adding a little plus to the experience.
Today you are just buying an expensive laptop, that you have to bring back to the Apple Store yourself (if you have one close by) if you have any issue. They doesn't cover some reparation costs that any other company would do. They are killing the 3rd party-reparation market. Also knowing that those devices are more and more fragile (seriously that keyboard on the latest MacBook).
Just stop buying those devices.
