Keep in mind there are new confounding factors such as using your mobile in daylight that also come into play. Not everyone has a new LCD monitor and my current LCD monitor isn't really any brighter than my CRT was. In my experience the Mac screens such as on the MacBook AIR have great contrast but they also introduce other issues such as glare because of their glossiness.
