For the few of you that don't regularly check the Kindle Fire product page on Amazon for changes, we've got a little update for you. Firefly, the visual search-slash-shopping tool that uses your camera to identify, and mostly purchase items, is coming to more tablets. Those with Fire phones, and the Kindle Fire HDX 8.9 have had the feature from the start, but it was notably absent on the more affordable HD 6 and HD 7 models. There's no word on when the update will land on your tablet (it's rolling out now), but if you're eager, you might want to add this page to your update checker too. Or, you know, just wait for mother nature (aka over the air updates) to take its course. While you do, you might want to start shortlisting friends with solid game collections for you to test it out on.
