Is it DC or Marvel, Windows or OSX? It doesn't actually matter, anymore. You get the best from both universes. You can run programs and open documents from both operating systems in their own windows, launching from either the OSX Dock or the Windows Taskbar. Parallels appears to provide practically seamless cut and paste, network connectivy, etc.
To add to the splendid geeky weirdness of it all, there's also this element to consider in the configuration linked to above.
