IT Trends bear a striking resemblance to London buses. 

You can wait ages for one to come along and then find that, annoyingly, three arrive all at the same time.  Think of it, as we came out of the dot com crash of the early 2000’s, things were relatively quiet in terms of major trends and then, seemingly from nowhere, we get hit with Cloud, Consumerization, Machine to Machine and Smart Grid to name but a few, all of which leave businesses looking at their IT departments with the same facial expression that a child has when confronting parents with their latest homework: knowledge and expectation.
