Has anyone used thunderbolt display(s) with the newer thin iMacs? I'm considering picking up a couple to go along with my 2013 iMac but am not sure how noticeable/annonying the different screen coatings will be. I plan to either VESA mount them on arms or use one of the number of stands to bring them all to the same level so I'm not worried about that part. Thanks for your thoughts!
