Pixel density comparison: iPhone 3 and iPhone 4

Clearly I’m not the first dude to weigh in here, but I wanted to get a real-world sense of the increased resolution on the iPhone 4’s “Retina Display.”

In these photos I’m holding an iPhone 3Gs in front of two computer displays running Apple’s iPhone Simulator. The Simulator is running a virtualized version of iOS 4.0.1 set to mimic the iPhone 4 device. The iPhone 4 simulator looks huge on the computer screens because today’s Macs have pixel densities in the 72-120 range, while the iPhone 4’s pixel density is 326.

Pre-dousing any flamey comments, I’m fully aware this is 100% unscientific so I offer this information purely for my own delight. That said, if you have something positive to share, surprise me. :-)

An iPhone 3Gs held roughly 30″ away from a 27″ iMac running a simulated iPhone 4 interface. Badass.

Same as above, but with a 1920×1080 display. I needed to hold the iPhone roughly 34″ away to get the sizes to match.
