Grand daughter is taking a web design course in college and they are telling her that she should use only PC web design software, yet the university is largely a Mac campus. Any reason for this bias and is there a work-a-around? She can purchase a copy of XP cheaply and buy the PC software but it seems wrong to me. Also, will she need Parallels? I am not a web designer so I really am in over my head. Thanks in advance.
