Given that until recently, OS X was only available at 60Hz, why are these forums not full of people bemoaning the terrible flickering? And if 120Hz is significantly better, would 240Hz be better still? what about 480Hz?
Do people really perceive a difference in fluidity of their displays given they already known that their new MBP is 120Hz? I would be very intererested in a blind test between 2 identical MBPS, one set at 60Hz, one at 120Hz. Then just carry out browsing, email, office work. Betcha most couldn't tell the difference.
