MacWorld just posted a review of Parallels 3.0 where they used the JumpBox for Drupal to test out the Virtual Appliance concept.

Like its competition, VMware Fusion (currently in public beta), Parallels 3 offers a selection of downloadable virtual appliances, which are pre-configured systems ready to be used with only a few mouse clicks. For example, I downloaded and installed a JumpBox virtual appliance set up with the Drupal content management system. Parallels recognized the virtual machine. All I had to do was answer a few Drupal configuration questions, and the system was up and running. I could then load the Drupal system from any browser on any machine in my home—in OS X or Windows. Using virtual appliances is an easy way to install and test complex software: there’s no configuration required, and if you don’t like what you’re testing, you can just throw it away when you’re done.
