Dieter Bohn Why don't all laptops have LTE?

Why don't MacBooks have an LTE option? Apple clearly knows how to make LTE devices — after all, it makes iPhones and iPads that have celluar connectivity. But for some reason, there's a werid divide between MacBooks (which Apple seems to view as desk-bound computers that can be carried from place to place) and the increasingly computer-like iPad Pro, which does get LTE. Do I just not get the difference between the two categories? 

On a less confused note, cars! There are so many cool cars this week at the Geneva Auto Show. You should check those out.
