I'm sorry but
1) This is a given
2) If you bought a 1st gen iPad Mini, you're an idiot who's asking to get disappointed when the new one comes out with a Retina display
3) You're rich and have the Mini and will buy the new one next year anyways cause you can.
in your inability to be reasonable, you forgot
4) You bought an iPad mini because it works for you and don't really care if the next revision has a retina display because that wasn't important to you.
which is the category i fall under.
