If you're the type of person who dreams of a future where you have your own personal Jarvis, Amazon Echo might be it. Now available to the public, the voice-activated home hub can control just about anything with a hands-free, verbal command.
Echo has been invitation-only since November 2014, and it's been updated along the way. Connected to the cloud and always getting smarter, Alexa (how one addresses Echo) is part Bluetooth speaker, part personal assistant that can control smart home objects like Philips Hue lightbulbs, reorder Prime products, access your calendar, give you traffic updates, and play Pandora stations and Audible books.
Echo is available to pre-order in the US for $179.99 and will ship on July 14.
