I've decided that I'm going to buy a refurb MacBook and soon hoping to connect it to a ACD. I've been reading reviews from Apple to Amazon to CNet and etc. The thing that I'd like to point out is that the 20" ACD is getting better reviews than the 23" ACD. Does anyone know why? I'd like to lean more towards the 23" because I have a 20" iMac and I would like a larger screen. I've read numerous issues of "bleeding" and "grainy" on the 23" but some of those reviews were back in 2006. I know Apple updated their displays sometime last year. Are these updated models still having the same issues? So if anyone has had any hands on experience with these displays, with or without issues, please let me know. Thanks!
