Been using version 5 since March 2010. When I switched from a Pc to an iMac and didn't want to replace all my programs. This was the perfect answer a fantastic program, and it looks like V6 is even better. One (of three) options lets you open Windows just like another application on the Mac desktop which opens a Windows Start menu and off you go; So easy. I'm using it with Windows 7 (which I bought off Amazon) No reason now not to change to a Mac. (Be advised you do need a copy of Windows in order to use Parallels in the first place. It doesn't include this)
