touch them at what? alot of mac folks like to do graphics design - it is imperative to calibrate and have even distribution of light and good gamut - most bulb based LCD or TUBE sets require a good 30 minutes of warm-up before you can rely on it.
LED backlight technology can stabilize much faster - which is less power - less heat - less waste.
green/gaming/production(Graphics) are all fighting against each other.
I was thinking that all the bad panels apple makes get cut up into iphone/ipad 
keep in mind - alot of glossy screens are uncoated. the matte anti reflection goes on top of the glossy 

 (cheap lcd's) so think twice about matte MVA/PVA/IPS cheapness 

 colors will pop like a mofo on an uncoated glossy MVA/PVA/IPS in the right room like no matte lcd will .. but the reflections would drive me crazy at work
