I have a rMBP, but am looking to possibly go iMac soon. I LOVE the rMBP lineup, but altho I first purchased in case I got photo/video gigs that required one...i've maybe left my desk with it once, and not for a gig lol. Looking to get an almost maxed out 21.5 inch iMac to have more power at home for both editing/streaming games to Twitch soon. 2 questions tho on my purchase... 1. I've heard Yosemite looks bad on non retina displays and was wondering what thats about? Is this an issue that will persist in the final build because the icons/fonts were designed with retina more in mind? Is it really that bad? 2. Am I gonna feel horrible when I get one and then retina iMacs come out later this year or early 2015? My thought process right now is that retina iMacs will probably be expensive at first, or reserved for the 27 inch if anything, which i'm not going for anyways. Also, after a few issues with the retina screen while gaming/editing, I feel like it wouldn't hurt to have a machine to edit on that is more within the "standards" these days, until 4k and retina becomes the norm anyways. I'll still probably buy an iPad or possibly another base model rMBP on the side next year, when the integrated graphics really start to take off, but would a few months wait really be worth the wait, both cuz this retina iMac business and cuz i've heard iMacs look terrible using the new OSX version on it?
