Amazon released Alexa for developers to integrate with third-party apps and devices, and we've already seen the software pop up in both software and hardware applications. However, Pebble says that this is the first time Alexa will be available on "a fully-independent" 3G-enabled wearable. If the addition of Alexa has you ready to open your wallet, a $79 pledge will secure your Core ahead of next year's ship date. That's a $20 discount over the going rate when the device arrives.
