Does it come with a virtual sound card this time round? If not, the choice between Hyper-V and VMware is still one made mainly on "VMware can do more, why would I go with less for free, if I can have more for a minor fee that I can easily afford anyway?".
At the moment, VMware is simply faster than Sun's VirtualBox, and has more device capabilities than Hyper-V. Although that said, the moment Hyper-V offers the same device capabilities, VMware shall most likely be abandoned. Because after all, why pay for a product when the just-as-good comepetition is free.
