Title: A DISASTER
Review: This "software" is extremely slow, even on a new iMac with 4GB of RAM. Trying to turn it off causes the "pinwheel of death" to spin until the system is rebooted. The interface is unbelievably clumsy, and the documentation is a joke. I would give this product zero stars if I could. Stick with Bootcamp or else try a vastly superior product, VMWare Fusion.
