In what may be the most obvious Apple rumor in quite some time, the company is reportedly working on the next iPad with Retina display (5th generation), and will be taking design cues from the iPad mini. This means a thinner, lighter full-sized iPad with anodized aluminum backing and thinner side bezels. What isn't so obvious, though, is the timing of the rumor. When Apple released the 4th generation iPad just 7 months after the 3rd generation model, many wondered if it meant that the company would be moving to a semi-annual release schedule. We'll know for sure if the 5th gen tablet drops in March.
