How Are 7-Inch Tablets Doing?
By BRIAN X. CHEN
Apple is widely expected to introduce a smaller, cheaper version of its iPad on Tuesday, perhaps in response to the crop of 7-inch tablets that have popped up in the last year. But how are those tablets even doing anyway?

To date, Apple has sold about 84 million iPads. Amazon’s Kindle Fire, the second-best-selling tablet, has sold about seven million units; Barnes and Noble has sold about five million Nook tablets; and Google has sold about three million Nexus 7 tablets, according to estimates by Forrester.
