hi there,
I've got an Apple LED Cinema Display 27" 2560-by-1440 resolution. It is the latest model. It has built in camera, microphone and speakers. It is in superb condition, no dead pixels or scratches. Works great. I still have the original box. The monitor is not even one year old. Awesome for multitabling, its only 160 pixels less than a full 30", so it fits just as much without being a 40lb beast (good for travel). It has minidisplay port, so it will connect to any laptop with mini/displayport. If you only have displayport and not miniDP than you can get a simple adapter which is easy to find. My samsung laptop has miniDP build in so pops right in.
The new one is 1000 bucks, so i think $600 is fare for it being in mint condition.
Still under factory warranty.
I live near Lancaster, PA. I can ship anywhere. I only accept cash/moneyorder/westernunion etc. No paypal.
