An example among data-entry types is being able to use keyboard shortcuts vs having to use a mouse, It slows them down to have to use a mouse.
Another is the Microsoft Ribbon, where people had the old menu system totally memorized, and suddenly couldn't find anything because it had been "improved" and "re-arranged for you convenience". Instead of making it an option that you could toggle, it was a mandatory upgrade.
This is totally irritating, especially when the new version has improvements that are geared to the enterprise, or software profit margins. I have talked to too many people who would routinely tell me this. This is a minor point of contention.
I still have an old computer that works just fine thank you, and run an old word-processor without a lot of this extra fluff. Heck, George R. Martin uses an old dos word processor because it is more convenient for him.
In this context, I am reminded of the old video about choices in spaghetti sauce. turns out, that in the world of spaghetti sauce, there is no one perfect spaghetti sauce, despite decades of advertising to the contrary.

Large companies like MIcrosoft are still in pursuit of "the perfect software" or "the perfect user interface" when they should give users options and choices when it comes to user interfaces and performance behavior. There is no one best interface, etc. just like there is not one best spaghetti sauce. While there should be an update for security reasons, etc. what does that have to do with the sort of an interface a person likes?
Similarly, there can be genuine product improvements when you do things a certain way, but also it is merely the pursuit of the cool and novel vs actual improvement. I upgrade systems because I need a certain functionality, and sometimes it is a royal pain when I cannot
I am a constant crank about software as a service. Especially if I can do what I need and keep a system running well for many many years, so that it is cheaper than paying a yearly fee.
