Actually the only thing keeping Apple afloat is their mobile division. They would have died off long ago, they have almost no share in the computer market.
Hmmm...no profits from Macbooks or iPads? You may want to check your source.
Also, Lenovo manufacturers everything Apple does. PCs, laptops, tablets, phones.
I'll guarantee that Apple makes more profit on any of those categories. ps. each category has a sort of reputation for the screens Apple uses
