Amazon’s new lineup includes 8-, 11- and 12-inch devices, with prices reported from $230 to about $550. The shift to full Android and Google Play removes a long-standing Fire tablet limitation.

These are not replacements for a powerful iPad. The interesting use is a cheaper dedicated home-control display or smart-home interface, if the software works as promised.

What to do: Compare the 8-inch model’s actual features and price with an existing spare device before buying.
