I don't think 2 years is too old. I've been running my ACD for 6 years and still looks great. The beauty of an older monitor is you can see if it has any pixel defects before you buy it. If it does, you don't have to buy it. But if you buy an Apple display brand new and there are dead pixels, they may not accept a return. Apple may be different about it now, but when I bought my Powerbook in 1998, there were a couple of stuck pixels. I wanted to send it back, but the company I bought it from said Apple wouldn't let them accept it. In my mind, a 23" monitor with 2 years of proven reliability is much more attractive than a 20" with no track record.
