Built from the ground up for the Mac, VMware Fusion leverages nearly a decade of virtualization expertise to harness the full power of your Mac hardware, while still supporting Windows-only applications, USB 2.0 devices, 64-bit, and accelerated 3D graphics.

This is the latest Fusion your Mac that will enable you to use a virtual operating system on a second monitor. If you own more than one monitor, or work across two monitors, you could open Windows as a virtual OS on one and then use your Mac on the other.

Within Fusion 2, you can now import a virtual machine from Parallels or the old Microsoft Virtual PC (for Mac). There is also the option to convert your existing Bootcamp partition in to a virtually hosted operating system.

Other highlights include the facility to print from a printer connected to your Mac, from within Windows, without having to set up access within Windows. The user-interface has had a makeover and it’s now more Mac-like than ever. In addition, there are many minor improvements to networking, unity and more.

Brand new improvements include 12-months of McAfee Anti-Virus protection for your Windows virtual machine, a rollback option and many other improvements and fixes. You can now allocate up to four CPU cores for each virtual machine.

Sadly the trial version can't be directly downloaded from the VMware website. You need to start an account, then login, to download.

The latest 2.0.5 has experimental support for Snow Leopard, will enable you to host a Ubuntu 9.04 operating system, reduced CPU usage and many more fixes.
