So I found a used Apple 24" Cinema Display for around £400, and was wondering whether it would be a good purchase for me. I'm going to university soon and I'm going to need a display to use for my 13" MBP and perhaps my PS3. Am I able to connect my PS3 to this display? And will the audio also be outputted? Following on, will there be any degradation in the quality of the image over the years that it has already been used by another person? And will the quality be comparable to that of the MBP screen but on a much larger display? I know I have a lot of questions, but I've never bought a display before, especially one this expensive. Thanks for any replies.
