years and years after the rest of the industry has embraced this technology
I would like some serious sources on this, please.
Because to me it seems that the rest of the industry (We're talking mobile computers, right?) is currently struggling with finding ways to market and sell touchscreens.
For most (even high-end) laptops the touchscreen is optional.
None of the main desktop OSs (Windows, macOS, ChromeOS and Linux) offer a mature touch-first UI, there are always tiny buttons and context menus to hit and none of them are even close to the fluidity of, say, iPadOS navigation.
There are 2in1s and convertibles that try to solve the problem of touching a wobbly laptop screen by ridiculous tent modes that look stupid and absolutely unprofessional, or by tilting the display all the way back under the body of the machine, so that you keyboard is now the underside of the machine and whatever you place the device on, you place your keyboard on, so that it gathers dust and dirt from everywhere and it still look stupid. Or there are mechanisms that allow you to rotate the screen, so now you device has a single tiny hinge that can loosen up over time and make the whole thing even more wobbly.
So yeah, that's far from 'embraced', more like 'clueless' I'd say.
