Right now, for around $50, you can buy a brand new Amazon Fire 7 with 8GB of internal storage. For a bit more, you can get a model with 16GB of storage. The Fire 7 comes with a 7-inch screen and built-in Alexa voice assistant capability. The device lacks serious battery life — 7 hours is the max quote — and the low-res VGA front-facing camera produces less-than-ideal videoconferencing results. The Fire 7 does not come with 4G capabilities.
