I have always used a PC for my computing needs. However, my daughter is majoring in photography and was told she should understand how to use a Mac. I understand that Mac has always been the choice for graphics. However, with the speed of the new PC's, I do not understand how the Mac can perform better than a PC for this function. I need to understand this so I can make the proper purchase to help my daughter. Please let me know more about the Mac. And..., thanks for your info.
