I tried it out and I can say that I liked it a lot. At first there were problems with download link but the support staff quickly sorted them out. At first glance I haven't noticed any major bugs. Have been using for several weeks now, hasn't crushed ot once. What I like the most is the amount of pre-drawn shapes and templates, helps me out a lot. The xml support for visio is a very convenient feature for me since some of my colleagues use visio. Overall, I would say that it is a highly potential program, useful for professionals.
