Amazon.com’s new Kindle Fire offers a disappointingly poor user experience. Using the web with the Silk browser is clunky and error-prone. Reading downloaded magazines is not much better. Still, user testing with the Fire did help us understand what the new generation of 7-inch tablets is good for: Are they more like 10-inch tablets (e.g., the iPad) or more like 3.5-inch mobile phones? To give away the conclusion, the answer is: “a bit of both.”
