Virtualization on the Mac has had to move forward rapidly in the past several months: where it was once enough to run basic tasks in Windows XP, users increasingly expect an experience much like what they would have in Boot Camp. That's all the more true with the launch of Windows 7, where the visual effects are not only useful but often essential. Between this and the changes in the background brought about by Mac OS X Snow Leopard, VMware's Fusion 3 has much ground to cover. We hope to find out in our review whether it's an essential upgrade or simply nice to have.
