that's interesting considering Apple's high end display is currently 30":

"The 30-inch Apple Cinema HD Display delivers an amazing 2560 x 1600
pixel resolution. Designed specifically for the creative professional,
this display provides more space for easier access to all the tools
and palettes needed to edit, format and composite your work. Combine
this display with a Mac Pro, MacBook Pro, or PowerMac G5 and there's
no limit to what you can achieve. "

i would assume that they would continue to grow their displays.  but
eventually i guess you could get too big...  could you? :)
