Avid readers on Android have some exciting new toys to look forward to in the latest version of Amazon Kindle. Update 4.8 adds some significant features to an already-packed app, specifically linked to in-book search. "X-Ray" is a proprietary system that downloads a pre-configured, collated file that includes information about the book itself, the characters, the setting, and the context of basically everything. For complex fiction, non-fiction, or textbooks, it's an amazing system previously reserved for the Kindle e-readers and tablets.
