Alexa's move to the tablet is a bigger deal than you may think

On Thursday, Amazon announced that it is adding its voice assistant Alexa to its Fire tablets for the first time. The voice assistant has previously been in Amazon's Echo, Fire TV and Fire Stick devices, but will launch with the new, low-priced 90 Fire HD 8 tablet that ships on Sept. 21. Alexa is also coming to the Fire HD 10, Fire and last year's Fire HD 8 tablets via a free over-the-air software update in the coming months. This move is significant, as it puts Alexa more at odds with Siri, Apple's voice assistant, and pitches up the simmering competition in the voice-assistant space. The end game of all these voice assistants is to become an integral part of users' lives.
