    I am pretty happy with the updated iMac,but I was waiting to see if the display would be upgraded to led backlight.
    Didn't Apple say that this year all of their displays would be led backlit!!
    So,when can we expect for them to be updated.
    Power consumption is a factor for me,I live in a house (in Indonesia) with a lot of rooms rented out,mains is only 10 Amps (2200 Watts)and we have occasional power cuts due to overload,especially around diner time.
    Anyone knows how much the difference in Watts it would be in between a conventional (Old) 24" display and a led display.
    If the diffence isn't that much I will buy now.
    But I guess its probably about 80 Watts less,or am I wrong.
    Cheers Perry

    #2 you mean a backlit KEYBOARD? o.o cuz displays arent backlit as far as i know..
    i dont exactly know the watt difference but i do know that led displays are more power efficient and are brighter as well

    All LCD panels have Backlight,without backlight you see very little.
    If the backlight is broken you are still able to see Your desktop but you have to look at your display at a certain angel and very nearby.
    Look through a slide at a black object or light object,thats about the difference.

    I just found this on Wiki:

    However, there are challenges with LED backlights. Good uniformity is harder to achieve especially as the LEDs age with each LED possibly aging at a different rate. Also the use of three separate light sources for Red, Green, and Blue means that the white point of the display can move as the LEDs age at different rates. Power also can be a challenge. Though it is possible for an LED display to be more power efficient, this is not a given and many first generation implementations may use the same or more power than their CCFL counterparts

    So,80 Watts less,guess not and I am not so positive now about the quality.
