"it's hard (to) remember a time when PCs ruled the tech world" Really? We (a small Consultancy and VAR serving professional offices and SMB) have had record hardware sales this year both in servers and client machines. Guess what? In several hundred client computers sold only one was a convertible/tablet type of form factor. Most were desktops and a handful were laptops. I have noticed a shift to smaller machines, for example most of this year's desktops were Lenovo Tinys since they take up very little space and have the same capabilities as a full sized tower or desktop form factor (minus the card slots which nobody in business ever uses). I'm going to assume that the creator of this article is talking about the consumer market since the business market doesn't resemble these remarks in any way.
