Is it not more the case that Apple users only like change once Apple have announced and implemented that change?
These forums are full of people bashing the competition, but when Apple adopt their features, suddenly the forums fill with praise.
I think you might be correct when it relates to either a new "feature" or a new device. But I certainly disagree with you in many other areas. There has been a lot of anger at Apple over many things.
Just off the top of my head…
1. Original iMac kills the floppy drive. Business gives Apple the middle finger by creating the USB floppy drive which it profits on by selling to outraged customers.
2. Death of OS 9 declared.
3. Death of Rosetta declared (Rosetta let PowerPC apps run on Intel Macs, removed in Lion).
4. Death of PowerPC
5. Apple forcing arbitrary system requirements. Example, OS X Leopard will run on PowerPC Macs with a processor of less than 1.0 Ghz.
6. No going back to previous iOS version if you updated.
7. Certain and arbitrary versions of iTunes required to sync with certain iPhones. For instance, iTune 10.7+ is required to sync my iPhone 5. But 10.6.4 is the last I can run on a PowerPC Mac.
8. Introduction of MacBook Air with no optical drive.
9. iPhone 5 with larger screen. Ohhh, the rage expressed here in these forums!!!
There are plenty of others. My point is to show this as an example that every time Apple changes something, there is a segment of Apple users who get angry at Apple because they have to change. They either have to buy something new or change how they work or both. Apple's doubling down on the change continually marginalizes them over time.
