II just thought I'd let you know in case someone wonders.... I went and bought the new iMac24 and also the 24'LED Display.
I set them both up and compared them at home. The iMac has a blueish tint (visible on a white screen) while the LED has a yellowish tint. The blue tint is certainly more pleasant than the yellow.That being said, I prefer something more neutral.
I went ahead and played with the settings and was able to get the LED to look just like the iMac and viceversa.
I didn't find ANY advantage in keeping the LED screen. The iMac screen is beautiful, for browsing, watching movies and I feel no need for the LED screen. If anything, the iMac feels brighter and super cool.
I strongly recommend the iMac, as opposed of a Mini with an LED display.
I'm taking the LED display screen back to the store for a full refund. They couldn't set it up there at the store one next to each other, so my only way to know for sure was to try them both out at my home. Worth the effort, and I'm now sure I have bought the right thing!!
