It's September, and that means it's time for fresh Amazon tablet hardware... only this year, software is the real star of the show. The internet retailer has introduced a new version of the Fire HD 8 that represents its first tablet (or really, mobile device) with Alexa voice control. If you're in the US, you can use Amazon's familiar assistant to play media, launch apps, deliver news and otherwise save you a load of screen taps. The feature will reach the previous HD 8, the basic Fire tablet and the HD 10 through an update in the "coming months," so don't feel pressure to toss out your old device if you're only looking for Alexa support.
