There's a long sliding scale from "knows how to use most features of the new software" to "uses every single feature maximally and never, ever presses the wrong hotkey because an old muscle memory happened to fire". I don't think the latter is a reasonable bar to set for "get used to the new software".
Then again maybe I'm being unfair here because if I'm really honest about it, the reason I didn't switch over to Chrome was that you couldn't start an in-page text search by hitting the / key like I was used to doing in Firefox. (I've since found many other reasons to keep using Firefox but at one stage that was the sticking point...)
