Resolution Independence

A friend of mine loves her new 27" iMac but has complained at how small everything is. Searching around on the net I found that it has about a 109 dpi pixel density. I also saw today that the new Nexus phone has a pixel size of 800x480 (as opposed to my iPhone's 480x320 pixel size), and the two together got me thinking more seriously about resolution independence again. Other than making big icons for my apps, I had pretty much ignored the resolution independence issue.

Today I fired up Quartz Debug to set the UI Resolution to a bigger scale, and I am happy that my applications did OK.


But how accurate of a test is this compared to real-world resolution independence?

Or in other words, is there real resolution independence built into Snow Leopard for apps? Can I (or my friend with her 27" iMac) set a scale factor on an application without using Quartz Debug?

Is there something similar for iPhone development?

Or is the Xcode mailing list a better place for this question?

Thanks,

Todd
