Apple uses it in all their iPad and iPhone ads (e.g. Do more with iPhone). A while back a reporter called out Apple on their un-grammatical naming and an exec justified it saying that leaving out the "a/an/the" on their products made them seem more alive and less replaceable. It shows there's a deeper connection to the product and Apple wants to convey that message to their customers.
So yes, it's bad grammar but it's here to stay.
