You're right. People do generally resist change. The important question when it comes to productivity is 1) whether the change represents a one-time "switching cost" or an ongoing process change; and 2) the total amount of effort and time required to use the new process/tool as effectively as the old one.

That's very likely an edge case which will affect very few users, but my point is that ergonomics and usability matter a lot for high frequency tasks, more than many people realize. It's not as simple as just "getting used to be different way of working."
A good example would be the transition from text-based word processors like WordStar and WordPerfect to WYSIWYG word processors like Microsoft Word in the mid 1990s. MS Word was much more popular for low intensity writing such as short memos and other typical workplace tasks, and the ease of formatting in Word helped it win the market share war. However, it was never as efficient for rapid typing of long-form texts with minimal formatting requirements such as academic writing and legal briefs, so that the older, more efficient applications remain in use as niche products in certain industries.
