Apple's reveals iPad Air at 16 ounces, iPad mini at $399
Apple Tuesday announced its "biggest step" with its tablet line, but took only about 20 minutes out of its hour-plus presentation to do it: a years-in-the-making slimmed down version of the 9.7-inch iPad, now dubbed iPad Air, and a high-resolution display for the 7.9-inch iPad mini. The biggest shock: a $70 price increase for the smaller tablet, to $399.
