Don't drink the koolaid!! Don't get a Mac.
Kurts' advice is dead on.
As for Macs being more secure, don't believe it. They are every bit as vulnerable as any other operating system. What they're not saying is that a Mac is less likely to get infected because they have such a small market share. That small number of users isn't worth the hackers time to hack them.
By the Mac users' logic you should download OpenVMS for your computer and run that. Since VMS is so old and its market share so small, anyone that could hack it is already dead! You'd be perfectly safe! LMAO.
