    Can someone please figure out the total screen area (in square inches) of the 20", 21.5" and the 24" imac.

    I understand that the aspect ratio has changed from 16:10 to 16:9, but I'm not sure how this affects the total amount of screen "real estate"

    Very good point. Widescreen specs vs 4:3 read bigger, but may not be.

    x^2 + y^2 = h^2

    Want: xy

    For 16:10

    16x=10y
    y = (16/10)x
    xy = (16/10)x^2

    h^2 = x^2 + y^2
    h^2 = x^2 + (16/10x)^2
    h^2 = x^2 + (256/100)x^2
    h^2 = (356/100)x^2
    x^2 = (100/356)h^2

    xy = (160/356)h^2

    xy(24) = ~258.88

    For 16:9

    xy = (324/801)h^2

    xy(21.5) = ~186.98
    xy(27) = ~294.88

    Disclaimer. I did not check my work.
