I've been looking for an older ACD for the past month since I thought some deals might be had since they are discontinued. Also, I'm not a big fan of the new glossy displays. I found a couple of deals and was wondering which you would suggest. In terms of size, the 20" would be satisfactory, however, the 23" would be ideal. 1) 20" ACD New in box - $480 2) 23" ACD Open Box - $395 Since the 23" has been discontinued since last year, I suspect that this may be the store's display model. I have to check it out at the store. The store does say it has the original Apple Care warranty. Is it possible to get information on the unit from Apple based on the S/N? My concern is the 23" unit may have been sitting as a demo for 4+ years. Is it risky to purchase the 23" display or should I just add extended Apple care and take my chances on the open box special? Thanks for your advice.
