Parallels and VMware Fusion are *not* Wine in a commercial or any other real way.

Parallels and Fusion are virtual machine monitors, they let multiple operating systems run on the computer hardware. Wine is a Windows operating system emulator (regardless of if the name tries to say otherwise). Wine has the benefit of not needing a Windows operating system, at the disadvantage of lots more compatibility issues, and well for some things you really want Windows, warts and all.
