Amazon's Echo speaker gains new features pretty much every week, but only starting today can Alexa tell you exactly where in the delivery process your Amazon.com orders are. You can ask "Alexa, where's my stuff?" or say "track my package" and find out the status of your incoming packages. So you can avoid obsessively checking your phone or computer repeatedly to see what's happening, and just nag Alexa instead. Alexa will also say who placed the order and when it happened. It's a little odd that it took over a year for Amazon's own digital assistant to gain these kind of smarts, but now you can add it to the long list of robust features that've been added to the Echo lineup since launch.
