iOS based laptops? What do you mean, why would you limit such capable hardware with an OS like that? They do have an iPad

So they can run dump Intel.

So they can release a laptop as thin as razor blade with a fifteen hour battery life.

So they can cream a percentage from every app written for it.

So they can make it impossible to run their OS on any hardware but their own.

Because they believe this will help keep viruses off the platform.
