Article misses key feature... Unity!

Completely misses the key differentiator between Parallels and VMWare in not commenting on the Unity feature. Unity lets you use an application inside a VM in "seamless" mode, in a similar way to the way Citrix provides published apps. It also lets you put Apps from inside a VM onto the Dock so you can call them directly without having to go through the polava of having to launch the VM first.

I think this is possibly the best feature that Unity has, it allows you to have a windows app and a mac app side by side and do copy and paste between the two without minimising or using awkward key combinations to jump between the VM and the host.
