I need to use a virtualization software to access hospital VPN on windows XP or vista. I previously used an old edition of parallels in the past, but looking at VMware fusion for the ability to install on multiple machines with one license. I see an offer on VMware's website to get the Pro version for half off from switching from Parallels. But would the standard version be sufficient for my personal needs? UPDATE: now wondering how easy it is to transfer existing VMs on Parallels 6 to VMware fusion 5?
