I would love to see Apple spend the next year or so refining iOS 11 and adding smaller features in this way. Because if this comes out in say, April, we have what 2 months until iOS 12 is announced, then it's basically back to a broken, unfinished, .0 release and another 6 months of them fixing it. Despite paying for a finished product, we pretty much only get 2-5 months a year with a decent OS (depending if you are a beta tester or wait for public release), then the process starts again.
Maybe carry on building on 11 for a while, make a really solid, feature-filled OS. It won't make the YouTube
bloggers very happy but oh well...
