When glancing at the iPhone 4 screen, it doesn’t look that fantastic. If you hold an iPhone 3GS or third generation iPod Touch next to it to compare, it is amazing. A few days after Steve Jobs had given the keynote for the iPhone 4, people claimed that the ‘retina display’ was merely marketing. It’s hard to deny what you can see (or rather can’t see) with your own eyes. I could not see a single pixel on the screen, it was just a sharp yet smooth image. Unfortunately, this amazing bit of technology will hardly be noticed.
