Steve Jobs just demonstrated the best feature of the new iPhone 4. The Retina screen has four times the resolution of the current iPhone.
The 960x640 pixels result in 326 pixels per inch density, more than our eye can resolve. This means everything on the iPhone 4 looks much sharper.
Apple also increased the contrast ratio to 800:1 pixels. The screen size of 3.5-inches stays the same. For me this new screen is reason enough to get the new iPhone 4 and put my 3GS to sleep.
