Sold my late 09 27" iMac yesterday. I couldn't take the heat in my office anymore, have mainly been using a 15" 8gb MBPr I got last year. Love it although the 256gb is not enough. Have a few questions about a new 27" iMac. They run cooler right? Will go top model with 16gb and 512gb SSD, will it be faster than my MBPr. Is the screen better than my old iMac as far as photos,video, Tv etc. How will I like reading on the new iMac, is it clearer than old mac but won't be as good as my MBPr right, will that kill it for me. Thanks.
