I was planning on getting a ipad mini with retina display in a few weeks, but I'm starting to get a bit nervous about the screen size. I'd like to be able to draw on my ipad and take occasional notes. I even got a ruler and drew out 7.9 diagonal vs 9.7 diagonal to see the difference. The screen size on the full size ipad at 9.7 looks massively bigger when they are compared. Unfortunately, I can't afford the ipad air so it would have to be either the ipad 4 or the ipad mini with retina display. I would love to get your opinion on the matter. Thank you for the help.
