The advent of last year's iPhone 4 caused quite a stir with its high resolution Retina Display. So, when the iPad 2 was announced, we were expecting to see that Apple's next-generation tablet would follow suit with a Retina Display of its own. It didn't, but that doesn't mean that it falls short when compared to its smaller iOS brother. Whether we're watching a movie, playing a game or browsing the web, the iPad 2's display really does impress, and as Dr. Raymond Soneira, President of DisplayMate Technologies points out in his recent iPad and iPhone display shoot out, the two iOS devices are like two peas in a pod -- or, as he puts it, Arnold Schwarzneggar and Danny DeVito's characters in Twins.
