Hi there, It is my understanding that parallels uses much more RAM then vmware fusion, and vmware fusion is offering more functionality with it's latest release. Anyone using/used both that can offer pros/cons? My main purpose is to use IE7 to print paypal shipping labels, as paypal does not support macintosh. So i need to run software for dymo printer as well as an HP printer. I would also like to run an older version of Quickbooks. Aside from this, I have limited need for a PC. I am trying to determine best option as I understand that with either, XP freezes commonly. I love the ability to drag and drop files from pc to mac. Thanks for your honest feedback!
