PC girl here! 15 years ago the school district decided all the student computers (labs and teacher stations) would be Macs and the administrative computers (office) would remain PC. Well of course, the teachers were alway contacting me to fix things on the Macs and it drove me crazy because I am not familiar with Macs. I would always manage to figure it out but talk about your basic nightmare! Now all the student computers are PC again and my life is much easier.
I am sure Macs are fine, but I love PCs. It's all in what you are used to I think. My step brother always manages to talk my mom into buying Macs. Then when she can't figure out how to do something, she calls me. I keep telling her Mom, if you would just get PCs I could walk you through just about anything over the phone. Instead, I have to go to her house to look at it and fiddle with it. Grrrrrrrr!
