Good call.

I think the thing the people really don't like is the feeling that they aren't in control.

When things don't change, people can feel like they are in control because they don't won't it to change, and it doesn't.

When people make a deliberate decision to initiate or accept a change, then again they feel like they are in control (they may have been manipulated by clever advertising, but that isn't relevant - they *feel* like they are in control). So hybrid cars etc are easy to explain.

When someone decides to accept a software update and there are little changes, they might not like them but they can probably accept it because they chose to perform the update after all.

But when you accept an update and it causes big changes, then the effect seems out of proportion with the decision and you get a strong feeling that you are out of control. *That* is what people don't like. Ever.

So I recommend small continuous changes which are - where possible - selectable ("Would you like to try the new Frobnicator widget once(1), every time (Y) or not now (N)?[1/Y/N]").

I call this "Evolution, not revolution" - I bet no-one has heard of that idea before...
