I've never considered Virtual P.C., but my Dad and I were at the Apple Store the other day (Picking up Tiger), and we had time to wait. We were looking at this wall of software, and we started looking at Virtual P.C. He started working on Mac in the early 1990s, and has always loved them. He has to use a P.C. for work and complains about it a lot. I tell him that he should switch to a Mac, but then he says he can't run the applications he needs. He has to be able to run Microsoft Outlook and the accompanying calendar program, and also he has to be able to log in via VPN. My question is how reliable is Virtual P.C.. Is it a resource hog. Also, lets say your in the Virtual P.C. in Outlook, and someone sends you an Powerpoint, Can you open it with Mac Powerpoint, or do you have to use a window version. Could someone share their experiences. Thanks in advance.
