No, I haven't. However, I am (was, rather) one of those forced to experience their decision-makng and Microsoft's enterprise tools for the better part of a decade, along with what I can only assume to be millions of other employees who were just ecstatic and excited (sarcasm, obviously) about these tools.
No wonder we love coming home to our Macs. The IT world that is manifested in typical offices is the ass-end of the tech user experience.
Using MS Office in the workplace is nothing to brag about. It's really about having to put up with a necessary evil. all do it because we have no choice in the matter. The enterprise sector is crying out for a serious refresh - for better, more user-centric tools that are actually a joy to use. And there is a silent movement in this direction, which will only become stronger with time. Unsurprisingly, it isn't being driven by MS.
