Gone from a 20" iMac to a 27", the screen is phenomenal. Couldn't be happier. Thanks to allot of you - i spent a great deal of time reading through some of the advise on models before i purchased. While i didn't directly ask questions, it was fantastic that there was so much information already on here. And yes i bought a full sized wired keyboard separately - can't stand the compact wireless ones they come with.. to small.
