Considering that Apple isn't going to be refreshing their ACD anytime soon I decided to purchase the 27in iMac and use it as a Monitor to my Mac Pro. I already had 2 24in ACD hooked up to my Mac Pro although now I finally have the setup which I've always wanted with the 27in iMac. I know a lot of you will say this is waste of an iMac but when Apple releases an updated 30 ACD I will purchase that and use the 27in iMac as an actual computer. I had to wait till I received the Mini Displayport to Mini displayport cable from monoprice but I finally have it setup and I have to say the screen is amazing. One issue I've noticed is that I'm not able to adjust the brightness of the iMac when it is being used as a Monitor, although I don't a USB connecting my iMac to Mac Pro which may be why. I've also noticed when set to full brightness the iMac screen doesn't get as bright as the 24 ACD. Let me know if any of you guys have are using the iMac just as a monitor and if you can figure out how to adjust the brightness of it. Overall I love the new screen and look forward to when Apple updates the 30 ACD or comes out with a 27 ACD.
