Ther seems to be different experiences with users comparing the riMac to the previous iMacs. What I've noticed is that when I browse the web with my iPad Air which has a retina display and then start using my 2011 27" iMac and Dell U3014 they look a little distorted and blurry but after a few minutes of use they start to look pretty good. It think one's brain>eyes adapts to the new/higher resolution of the iPad and then has to make an adjustment for the standard displays. So maybe keep this in mind when doing a comparison at a store. You might be just as happy with a 2013 iMac if your not going to be using it for it's graphic abilities or want TB 2 or the 4GHz CPU upgrade.
