For those who, like me, crave screen real estate, particularly in laptops, and what to compare:

PowerBook 12" 1024x768 = 0.79 Mpx, 106.7 ppi
PowerBook 15" 1152x768 = 0.88 Mpx, 92.3 ppi
PowerBook 15" 1280x854 = 1.09 Mpx, 102.6 ppi
PowerBook 17" 1440x900 = 1.30 Mpx, 99.9 ppi
15" Studio Display 1024x768 = 0.79 Mpx, 85.3 ppi
17" Studio Display 1280x1024 = 1.31 Mpx, 96.4 ppi
22" Cinema Display 1600x1024 = 1.64 Mpx, 86.3 ppi
23" Cinema HD 1920x1200 = 2.30 Mpx, 98.4 ppi

(Mpx = megapixels, ppi = pixels per inch)

Given Mac OS X's typically larger font sizes, menu and other controls. I prefer the denser displays in the PowerBook 12" (106.7 ppi) & newer PowerBook 15" (102.6 ppi). I wonder if Apple would ever try to fit more pixels in the PowerBook 17" at some later date, say:

PowerBook 17" 1536x960 = 1.47 Mpx, 106.5 ppi

Would be lovely, wouldn't it?
