First, Kindle is introducing Kindle Singles, which Amazon describes as “Kindle books that are twice the length of a New Yorker feature or as much as a few chapters of a typical book.” It looks like Amazon is trying to attract writers who want to self-publish for the Kindle.
Amazon has also updated its iPhone app to include barcode scanning. It only works on the iPhone 3GS or iPhone 4. What can you do with it? Scan the barcode of an item and check Amazon’s inventory for it. You might save yourself some money if you’re out book shopping (or shopping for anything else, considering how Amazon has branched out).
