VMware Fusion is primarily aimed at Enterprise so the UI and documentation assume a level of competence. It runs smoothly and while boot is a little slow, running apps and programs within the guest OS is smooth and seamless. Once you allocate hard disk, RAM, video memory and ports to your guest OS, VMware Fusion trues to keep everything balanced. VMware Fusion manages system resources very well. Installing a virtual machine is more complex than installing a normal app and VMware Fusion does a good job of walking you through it. The program itself installs quickly and contains a very good setup wizard for both the program and the VM itself. It is fully supported, has good documentation and a very active community. It is a fully featured virtualization program that offers a lot of features for the money. VMware Fusion costs $79.99 for unlimited installations and is the little brother of VMware Pro.
