Have been a PC user for many years and finally purchased a MBP. What a treat to have everything on our network pop up automatically, drivers all there, no viruses, etc. Will take a bit to get adjusted to, but ever so happy. Unfortunately, I have 2 business programs that run on Windows platform only. Therefore, I need to install Windows XP on my mac and will run it off VMFusion or Parallels (not going to use boot camp). Questions: (1) For Windows XP - do I need to purchase another copy of it - OR - can I use it from my previous PC which I'm not using any longer? I have the original discs from the PC that's no longer being used, but I wish to do it all legally. (2) From what I read in the forums, it seems that VMFusion is liked better (less problems) than Parallels. However, most of the posters are people who have alot of experience with Mac OS. As for being a newbie, any recommendations? Thank you.
