Steve Jobs said during his WWDC 2010 keynote address that once you experience the Retina Display on the iPhone 4, you couldn't go back to a traditional display. It was that good. And, ya know, the Reality Distortion Field be damned, Steve wasn't exaggerating on this one.
I've had the iPhone 4 for about a month-and-a-half now and I'm totally smitten with the new display. The geeky, techie side of me never ceases to be amazed at the fact Apple was able to achieve such high pixel density in the same 3.5" space. The non-geeky "regular" side of me never ceases to be amazed at how everything's so freakin' clear and crisp. Text is razor-sharp. Album art is more detailed. Pictures look better. Even app icons have more definition. It makes the phone so much easier to use, even if, by nature, things on the screen are smaller because of the higher resolution. I don't care -- I'm willing to squint for such beauty. Without a doubt, the Retina Display goes to show how awesome Apple's design and hardware engineering teams are.
The Retina Display has me so spoiled that I think -- stupidly -- that my iPad's display is "low resolution" because I can see pixels. And the iPad's screen is nothing to sneeze at either -- in fact, neither were any of the previous iPhone screens, for that matter. Even though the iPad's display is larger (9.7") and has higher resolution (1024x768), it's only 132 pixels per inch. So text isn't as sharp and I can tell a noticeable difference in image quality. Here's hoping Apple brings the Retina technology to the iPad next year.
Steve also said that the display was the most important component of the hardware, and it's true.
There are only three words to describe this marvel: BEST. DISPLAY. EVER.
