Both come with free shipping and have an optimum resolution of 1920 by 1200 pixels.
The Dell monitor has 24 inches of viewable screen area, inputs for S-Video, Composite, Component, DVI & VGA connections, four USB 2.0 ports, 500 cd/m2 brightness and 1000:1 contrast. The Apple monitor has 23 inches viewable, two USB, two FireWire 400 ports, 270 cd/m2 brightness and 400:1 contrast.
Don't get me wrong, I really like Apple's hardware and especially like the aluminum bezel on their LCD displays, but when you consider that the Dell has analog inputs, better brightness and contrast and costs almost half of what the Apple monitor costs I'm forced in the direction of the Dell.
What's your take on the price gap between Apple and PC peripherals? Will you pay more for the Apple logo?
