Lt. Vulgar is completely correct.
I rather use ms-dos instead of a mac. Macs are not for gaming, they just do everything (except gaming) like windows but a lot worse... they have all those GAY commercials about mac being better then windows buts its all a big scam. YOU HEAR ME? IT'S ALL A BIG SCAM.

That video is the complete truth.
Ontopic solution: convince you gf to buy anything other then mac.
Remember that it IS a scam.
