And what real value is there to users in having windows do live redraws while they're being moved around the screen? That's decorative window dressing. And Apple could've supported both live redraws and outlines, using one or the other on a given platform depending on the processor and GPU.First, people talking about smoothly moving and resizing windows on old computers are forgetting that you were usually working with an outline of the window, not the full contents of the window itself. They didn’t have the power to perform the calculations to do it live for a good decade or two. Even then, there was a lot of lag! Apple is not going to publicly release something they know will reflect poorly on their product.
Previous iPad pros are incredibly powerful. What you're describing is trivial for the processors on these platforms. They're as fast as Intel 11th generation mobile processors.Second, iPad apps are not designed like desktop apps. They may not all be built around being resized. There are still apps out there that don’t support features like split screen. Apple has to code workarounds for apps like this, and that will require extra processing and memory.
It's precisely one of them.Third, non-M1 iPads do have external monitor support, but it has to be written into the app. The springboard does not resize to an external monitor, probably because the interface is so obviously touch-based. Mouse interaction was an afterthought.
There are plenty of things Apple does that are worth complaining about, but “Apple didn’t give me a free new feature for an iPad that was never advertised to support it” isn’t one of them.
