I wish them the best of luck. Yep, no-one likes change, but often times it ends up better than it was before. I know that from wifey. She's so often bought me something I did not like at first, but after I got used to it, and admittedly I ended up loving it.
Just give it a chance, keep an open mind, and if in the end it need improving, they'll certainly make the necessary changes. Change is not easy, and I do see their need to be mobile friendly, that's a fact these days. Everyone spends so much more time on their smart phones than behind a computer.
