At some point these phones are powerful enough that we need to be able go get a desktop experience that can run macOS. Why is a 600 dollar neo more capable for productivity than a 2000 dollar iphone with a much beefier chip?
Canonical was simply 14 years too early, but we are rapidly apporaching this vision: https://arstechnica.com/gadgets/2012/02/ubuntu-for-android-c...
I mean, we still have the ridiculous separation between the Macbook Pro and iPad Pro with the same processors where you have to choose between a fully featured OS or a touchscreen. We are a long way from an iPhone being used in that way.
This is Apple's Achilles heel.
If another company could release something like the Duo that seamlessly switches between phone, tablet, and desktop experience and make it Apple quality then Apple are in trouble. The technology is all there since the days of Ubuntu Touch.
Sadly I don't think there is a company in a position to build such a device that could compete.
