Here’s an image of the Motorola Droid X next to the iPhone 4. We thought it was interesting because the Droid X has a monstrous 4.3-inch display, compared to the iPhone 4 and it’s 3.5-inch screen. However, the smaller iPhone Retina Display actually packs more pixels in, despite its smaller size. The iPhone 4 display resolution is 960x640. Over on the Droid X side of things, it’s 854x480. Sometimes size doesn’t matter—it’s what do you with the size you’ve got. That said, it’s way easier to watch video content on the Droid X than it is the iPhone 4, just because the screen has so much more room.
