I know this had been asked before but now the pricing between Dell and Apple is very close (Dell has really no deals at the moment) and I need to buy a monitor ASAP. For those who have owned these monitor (preferably those who have owned both), which one to you think looks better (price aside). I don't mean external looks but how the screen itself looks. I had a 20" Dell before and I was wondering if the ACD is better, the same, or worse? Is the backlight even on the ACD? Is it bright enough? How does color compare to the Dell? Also, how much better is the 23" ACD than the 20"..... would it be worth the extra $400 for that monitor? Thanks all!
