I am in the process of making the bold move to take my staff ( about 23 people in total of a location of 150) over to the Mac. We'll do this as part of the hardware replacement cycle. Most things my IT department has figured out, office, exchange support etc. We need decent charting and project management tools. Does anyone here have a long history with Omni applications specifically OmniPlan and OmniGraffle? I have used them as trials and like them a lot but I wonder if anyone here is using them in a heavy duty professional environment. OmniGraffle can export to a Visio format I know. How interoperable are these applications with Microsoft Project and Visio in general? Thanks!
