Apple sliced off a bunch of the vertical resolution compared to the 30" Apple Cinema Display. ACD 30" = 2560x1600 iMac 27" = 2560x1440 Not really a huge deal. I think they did it to make it true 16:9. I'm just posting this because this somehow slipped past my notice. I'm one of the people demoted from Mac Pro to iMac and now I am sort of wishing I could still use my 30". (I don't have space to use both.) Not really a big deal. Just an FYI. Yeah, I know it's my fault for not paying attention. I probably still would have went with the iMac 27" anyway.
