I'll be purchasing my brand new 24" iMac in the next few days (as soon as the Leopard date is announced so I can hopefully claim a free upgrade). In preparation, I was looking to buy Parallels Desktop 3. However, having now seen VMware Fusion I'm torn between the two. From what I understand Parallels offers a few more features but VMware is perhaps more stable and offers dual core support? For the purpose of running windows-only programs, some which may be quite intensive, which should I go for?
