From the virtualization industry leader comes VMware Fusion. Simply the best
way to run Windows, Linux, or Solaris at the same time as Mac OS X - without
rebooting.
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.
Say goodbye to the Windows desktop - seamlessly run Windows XP applications
just like Mac applications; use Exposé to switch between any application,
minimize to the Dock, bring forward only the application you care about, and use
familiar Mac keyboard shortcuts. Use the VMware Fusion Launch Palette to easily
access all your Windows applications, and keep your favourite Windows
applications in the Dock.
VMware Fusion 1.1 contains a number of new features including experimental
support for DirectX 9 and support for the iPhone under Windows. The Unity
support has been enhanced and much more.
Sadly VMware have changed the way you have to download their software, so you
need to be a registered VMware user to obtain access. This download points to
the form where you can register or login to download.
