As for moving to their cloud offering, all the prices that I have seen so far would indicate a massive jump in costs for most companies. It's true that there are some benefits to be had, but I would question if more than a few would ever actually see those.
But no doubt there are businesses that will ignore advice from those that know about these things, move across and then wonder why it turns into a major problem.
