I'm ready to pick up a 23" ACD from my local Apple store now that the price has dropped and specs are up. My question is, if I go in this week how can I tell if the display I'm getting is the newer specs or if they are dumping existing stock? I called the store and they are clueless. They said prices are down but the specs are the same. I want to pay cash otherwise I would order online. What to do??
