As with VMWare Fusion 5 there aren't many big perks over the previous version. Getting started with virtualisation can be a confusing minefield of operating system jargon and instructions. Here Parallels scores highly on our ease-of-use scale.
Getting started with your virtual operating system is easy. Even if you've not downloaded the software, Parallels will go and fetch the right thing, making the whole process simple. Within seconds you can be on your way to installing Ubuntu or even Android, you can get OS X Lion from your rescue partition and naturally, a host of Windows options.
