Help, Why people should buy PC over Mac

Hey guys, I have been a member for a while and I got a persuasive speech due tommorrow. I wanted to ask you guys, and sorry if this is posted in the wrong section I could not find a better one, a question about PC versus Mac.

How can I persuade my audience that using/buying PC over Mac is a better. Keep in mind that my audience are general students that don't game.

I need 3 problems, causes, and solutions on why Mac's are worse and the PC is a better buy.

Thanks in advance,

Pluke.
