Last week VMware released Beta 3 of its Fusion virtualization software for running Windows on an Intel-based Mac. Among several new features are two that are obvious attempts to overcome advantages offered by competitor Parallels Desktop: support for booting from a copy of Windows installed under Boot Camp and an Easy Install option to automate the process of running the Windows installer. This version also includes performance improvements and a simplification in the way virtual machines are packaged, among other changes. Fusion beta 3 is a 135 MB download.
