Apple should cease trying to reinvent OS X every 12 months, and focus on getting the OS working 100% across their hardware, I don't want new toys I want the OS to work without issue first, then add additional functionality. It`s ridiculous the number of users who have issue with Wi-Fi, Bluetooth and now power drain.
10.11 is a step in the right direction, ultimately OS X is not free as the cost is "baked" into every Mac, either Apple is waking up to it`s customers or are now concerned about sales with Microsoft`s Windows 10 looming. As many switched to Apple as there was no rational alternative to Windows 8, W10 changes this paradigm.
FWIW I have had no issue with my Mac`s equally so many others have, nor do they come across as not knowing what they are doing.
