I hope the retina display and better camera happens because I been waiting for this in the iPad 3 to become my first iPad. If it wasn't for the non retina display I would've gotten the iPad 2. Given the pricing I can't upgrade every year. So I was waiting.
Basically, my thinking went like this:
iPad 1: wasn't sure of I have a use for it didn't buy.
iPad 2: after seeing the success and functionality of iPad 1 I wanted iPad 2. But once I demoed it at the Fifth Avenue store I was disappointed after comparing it to iPhone 4 display and the camera. So I decided to hold out for possible retina display iPad 3.
Currently, I own my 2nd iPhone. A iPhone 4S upgraded from my iPhone 3GS and saving money for the iPad 3 and my first iMac the 27" high end.
Watch out, wanting a retina display on an iPad 3 in this thread will NOT BE TOLERATED!
