Amazon's New Echo Lineup: What's the Difference?

Anyone who's embraced Alexa likely has an Amazon Echo product to thank. Since 2014, the slim cylinder with the killer wireless speakers has been listening for its wake word, ready to set timers and give you the weather, among other things.

New features get added to Alexa all the time, such as making calls, support for multiple devices in one home, and music syncing.

At the same time, Alexa expands her virtual footprint to other interestingproducts and even software. You can access Alexa in apps like the Amazon shopping app, and as of this week, even the Amazon Music App ("Alexa, play songs by Peter Frampton") on iOS or Android. Heck, later this year, even the Cortana digital assistant will talk to Alexa and vice versa. If we could just get Alexa to replace Siri, we'd be set.

Alexa on an app is nice, but Amazon has some pretty cool hardware to house its virtual assistant, too. This week, it overhauled the full Echo lineup, adding gadgets big and small. If you're wondering which one to get, read on for a rundown of what each device brings to the table.
