Well, now that I have my old ipad1 back home (it's been out on loan) and have been playing around with it a little. The retina/non retina isn't that big of an issue for me. I'm seriously considering selling both ipad's and pick up a mini already now. And that's just from what you guys have been saying here.
I use my ipad for email, the odd website update, social networking and finding information when I am not on the laptop. I picked it up for it's ultra portability (as it was at the time) and now that there is an even smaller version that is still user friendly to the eye, the mini is a good option, me thinks.
But first, the WWDC and see what apple announces then.
