Almost everything you hear connected to Amazon these days would be about Alexa or the Echo. It's been quite a while since we've last heard from the retail giant's other smart devices, specifically its Fire line of tablets. Is Amazon done with tablets? Not quite! It has just unloaded four new Fire tablets, the Fire 7, Fire HD 8, Fire 7 for Kids, and Fire HD 8 for Kids, that offer the wealth of Amazon's digital content and services, including Alexa, at still ridiculously low prices.
