I admit, my title is misleading. This is a list of mostly "not likes" with iOS 11. Why few "likes"? Because there is enough written elsewhere singing the praises of iOS 11 and detailing "what's new". Maybe my dislikes will help you decide if (when) you want to upgrade...
In August 2016, GE's CEO said he wanted every new hire to learn to code. And I must say, I do agree! In today's digital, data-driven, self-service world, everyone should learn to code. But, to clarify, I'm not necessarily referring to programming in C# or Swift (like I do), but rather "coding" for automation.
I've updated my MacBook to macOS Sierra, and it's rather underwhelming and half-hearted IMHO. And yes, dear eagle-eyed reader, Apple capitalizes the Mac in MacBook but not the Mac in macOS - what a confusing naming (lack-of-)convention. Still, macOS is a better name than OS X (can you say OS 10 10.X instead?)
I've stumbled on another "feature" that iOS 10 has mangled - SpotlightSuggestions in Look up. What does this double speak even mean? Worse, I can't even get rid of "Look Up" and revert my beloved "Define".
I have updated to iOS 10, and so far, I'm really not impressed, since it brings so few features that I care about that work on my iPhone 6 and in my region.
About a month ago, I discovered Apple had imposed new limitations on the free Apple Developer account. This limits the period that an app can run on your phone to 7 days (due to Provisioning Profiles) and the number of changes you can make to the project (not the source code, but Capabilities like App Groups).
I just bought a MacBook Pro! Prior to this, I've only been exposed to Windows and a smattering of UNIX/Linux... until now. What really struck me was the price! Total sticker shock, and that was before Apple raised prices on 14 Oct 2015!
