So, what do you use to write apps for an iPad?
Let's say you're the kind of young hipster type that Apple would like to appeal to (and, in fact, do appeal to). The sort of person who likes to work in the kind of coffee shop where they can pretend to be cooler than they are. Are these people going to start turning up wheeling a trolley with a Mac Pro strapped to it, or what?
No, no, they're not: they're going to turn up with the same kind of shiny Apple laptop in their backpack they turn up with now, which is why Apple are not going to kill their laptop range.
