I'm going nuts trying to decide on which monitor to buy. So whats your opinion, is an extra 3'' worth 350+ dollars (ill be buying used)? The monitor will be used as a second display next to my 15'' macbook pro. I previously owned a dell 24'' LCD and found the size to be impressive but i'm not sure how it would feel in comparison to a 20'' display. O.. and a picture of someone using their Macbook Pro with A 20'' ACD display would be much appreciated!
