Small device, giant resolution. The new version of the little iPad now has a Retina display, but it's also thicker than its predecessor. Apple also bestowed their 64 bit A7 processor on the little tyke, so it's on equal footing with its big brother. Or is it...?

The Nexus 7 is 16:10, not 16:9. If you play a 16:9 video on a 4:3 (16:12) device, you can use 75% of the screen area, not 60%.
