Anyone know the DPI of the 24" iMac?

[Scott Anguish]

well, I did do that... but I wasn't confident in the results...

especially when you run Quartz Debug on a 23" display and look at the  
User Interface Resolution and it says 72 dpi

the calculation on the other hand gives you

(1920 * 1920) + (1200 * 1200)
= 5126400

sqrt(5126400) / 23
= 98.441542247547 dpi

which just doesn't jive.

that's why I was hoping someone could either run Quartz Debug, or my  
little app.
