Last month when it announced its two newest smartwatches, Pebble also made the Core official. This is the company's first non-smartwatch product. It resembles the iPod Nano, and Pebble bills it a "capable fitness device that lets you leave your phone at home", as it comes with built-in 3G connectivity as well as Bluetooth, GPS, and Wi-Fi. It also has a 3.5mm jack to plug headphones into when you feel like listening to music (which it can stream over 3G or Wi-Fi). The Core unfortunately won't be out until 2017, but when it does ship it will do so with built-in support for Amazon's Alexa...
