Don't think for a second that Amazon is going to let the rumored iPad Mini and Google Nexus 7 hog the small- tablet spotlight. After all, Amazon was first to market with a $199 device, with the Kindle Fire gobbling up more than half of the Android tablet market share before sales fizzled. Now here comes the sequel, which promises to beef up on features while continuing to leverage Amazon's vast array of content. Apps, books, magazines, movies, music, games — Amazon has it all. Meanwhile, Amazon looks like it's gearing up for a smartphone launch, having recently hired two Windows Phone managers and a former hardware developer from Apple and Nokia.
