It’s been a busy couple of months in tech. Today, Amazon held its big product event for the year, during which we usually get upgrades to popular devices. This year Amazon brought us a Nest competitor, Amazon’s Smart Thermostat, the Echo Show 15 and it introduced Disney to Alexa with Hey Disney. The Amazon Glow for kids combines video calling with activities and the Halo View brings Amazon to your wrist. There are more Blink products, and the Ring Alarm Pro lets a service monitor your home while you’re away — or the flying Always Home Cam drone can watch it for you. And Astro the robot brings wheels to Alexa, for $1,000.
