Parallels In Coherence Mode The new version of Parallels just came out (build 3186). If you want to run Windows on your Intel Mac, this is definitely the way to go, but you need a minimum of 2GB RAM - maybe more - for adequate performance. Check the MenuMeters in the Mac menu bar and you'll note that the CPUs are not maxed by any means. In coherence mode (as shown) both Windows and Mac programs run side by side - Windows isn't stuck inside the Parallels window any more - and the dock and Windows menu are both available. Very slick.
