Why is it that some people hate Macs so much?

Like honestly who games on a computer? If you do the only thing I can really think is worth it is World Of Warcraft. Anyways if you buy a computer than runs games smoothly it ends up costing more than a basic mac when with a basic iMac you can run Vista or Xp and do anything pc users can do smoothly along with the ability to run Mac OS X Leopard. Havn’t people even noticed that all Mac users have switched from Pcs?! We know whats better. Also for all the people complaining Macs arent compatible with anything look at this.

Mac Compatibility: Windows, Linux Mac OS X
Pc compatibility: Windows, Linux

So if you think about it Macs are more compatible. This is more of a debate than a question and im really interested to hear your answers.
