Hey so my sister is thinking of getting a macbook but she needs to use windows for work purposes... I have a few questions before I advise her to get anything.. 1. Which is SIMPLER to use for someone who has basic computer skills? VM Fusion or parallels? 2. Can I install the windows 7 student download onto this? or do i need a previous version to install then upgrade with the 7 student download? 3. will the 2GB ram in the macbook be enough to run multiple apps with windows open as well? or do I need to up it to 4GB?? Thanks for the help.
