Missed the point
John_LI_IT_Guy, I think has missed the point of the article. I don't think that the writer is implying that IT can and should support every app that someone chooses to use. Instead, it is a call to all of us, IT Staff and users to broaden our horizons beyond our immediate circle of influence, expertise, etc in order to be better prepared to take advantage of opportunities that present themselves as challenges.
Unfortunately, the Johns perspective is all too common within the IT community. No one said IT was going to be easy, and I suspect that it will continue to be so, for many years to come.
