1366x768 is an ancient joke, just as bad as the 1280x800 of the old 13" MBPs. The 1440x900 of the MBAs were already more useful, and the bare minimum I would recommend today for mixed causal use.
In regard of the topic - can't believe many people are switching to Apple just because of the M1. But I can guess many people, including myself, are leaving from Apple soon. Why? Because they give up more and more standards/compatibility, like x86, Bootcamp, 32bit, CUDA, OpenCL which is just stupid if your OS market share is hovering around 10% and less. Yes, progress is important and good, but just like their idiotic MacBook ports decision, their way is too radical and prosumers + companies are getting annoyed.
Remember when Macs had been solid Machines for 3D/CAD once? Guess what, Windows and Linux are the way to go now. One example: The Blender developer team had always struggled with the poor OpenGL/CL implementation in prior OSX versions, and now, since it got entirely ditched for Apple's proprietary Metal bs, they stopped GPU rendering support in version 2.8 and newer. You have solid hardware, like a Radeon 580, Vega 48 or even XT5700 built in? Entirely useless in Blender now, because de-facto you have no OpenCL, no CUDA, no Vulcan, just Metal. And from now on, no more Intel either, but own chips. You think all software manufactures gonna transcode their apps for said 10% market share? The big guys, like Adobscription for sure, but for the rest, I doubt so.
I gonna keep my MBP 2015 and iMac 5K 2017 with Mojave as long as I can, but then I guess, time to leave, as much as it hurts. Their mobile devices are great, my Macbook is still a badass DJ/audio machine, but I don't like the path they have chosen. Luckily, customers have the choice to go their own path.
The question is how many casual users can they entice with the new M1 Macs? I know the original MBA was a gateway drug for many new Mac users.
Honestly, more users just need a basic machine to handle office, web, video streaming, etc. The entry level MacBook Air offers that along with excellent battery life, good thermals and silent operation.
