As an IT guy, we have to either embrace these things or face lack of jobs and desired skills as this is where stuff is going.
We are realizing at work, that Exchange 2013 is most likely the last on premises setup we will have. MS is making the 365 offering too appealing with features that will only be made available in 365. And they will continue to mark up the on premises price to the point where its not financially advisable to run it any longer. Office365 for business is offering unlimited storage per employee. I'm not sure how they can even afford to do it, for the price they charge..but they do it.
