Has Apple invented anything original?

As much as an Apple Computer fan as I am, it is hard to argue with this video…

After watching this, the only thing Apple seems to have invented was the unibody case. They take a solid block of metal (e.g. aluminum) and use C&C machines to carve out each laptop.

And according to this patent, Apple invented the super-cool MagSafe power connector.

Question: does it matter if Apple takes other company’s products, change them and call it their own?
