Sorry to hear that, too. To avoid a lot of initial negative reaction like that I first imitated the look of my old board as much as I could - then "made them a part of it" by accepting their input and making some changes that they wanted
before I switched over permanently. My "beta" was actually up a couple weeks so they'd get used to it, and learn how to use it, side-by-side with the old live board. But in the end, being the one paying for it, I always have last say.
So the key that would help would be to 1) show personal excitement, and ease them into the idea, and 2) make them feel apart of some (minor) decision making.
