This survey lacks some important info. First off, those responding to the survey, what makes them respond the way they are? Are we looking at peoples most best hopeful guess or are we looking at actual informed responses, based on real on the ground decisions in the works?

All this cloud computing talk is lovely but when ever the hopefuls start talking about cloud computing and their notions that its on the verge of taking over we never hear the explanations for how the problems related to cloud computing are going to be resolved so that cloud computing even has a chance of reaching 50%.

It always seems too much of the "If we say it often enough it will just happen" philosophy, as opposed to addressing the concerns frequently expressed about cloud computing and how that will get cloud computing to where they propose its going to end up.

Over 50% by 2015? Maybe, but not just because thats a prediction, it can only happen if the concerns about cloud computing are fully addressed well before then and as things sit today most of those truly betting on cloud computing seem far more interested in making bald predictions of where cloud computing is heading as opposed to describing how the problems with cloud computing are going to be fixed, and at that rate 2015 is way too soon for over 50%.
