Well, what about Adobe Creative Suite, for instance? I work on a 27" Retina screen, use a mouse for precision input and am able to sit a distance from my screen, with my keyboard and mouse within easy reach, sitting in a position that's comfortable to me. I don't want to be hunched over a 12" screen (I've even opted for a 15" MacBook Pro due to its extra screen size over the smaller Apple laptops) that I can't even use on my lap; I don't want to have to type whilst holding an Apple Pencil (picking it up and putting it down on a regular basis wouldn't be condusive to a balanced workflow) and I want a structured OS that doesn't rely on the Cloud and lacks a desktop-style filing system that, as a Mac-based Professional, I've been used to ever since I started using 'a computer'. I'm afraid it can't replace 'MY computer'. And, as some have previously mentioned, if Apple are going to adopt this marketing strategy, and people fall for it, then in the initial we'll be waving goodbye to the MacBook Air and then incrementally, the more useful Macs will start to disappear as time and tech move on. In no way am I convinced that this is a viable proposition and, what's more, if the current lack of Mac updates is in any way close to being a by-product of this thinking, Apple may well have cut their own throat. Here's hoping otherwise...
