Ok, I'm going to throw this out there just to see whether one over the other is better. I'm hearing that the Dell has better peformance and less expensive. I would be using this for Photography and Video editing so I may buy two of them for dual monitor. I just want to know whether the Mac 24" Display holds it's own in comparison to Dell. I will be using these monitors with my newly purchased 17" Macbook Pro. We'll see from there.
