Amazon Kindle buyer's guide: What to know before you shop

Because the Kindle is designed just for reading, the black-and-white screen will keep you focused without distractions from texts, apps and social media. You'll get up to six weeks of battery life on a single charge, and the 16 GB of storage provides room for thousands of books. 

The Page Color feature lets you invert black text and a white background for a more comfortable reading experience in different lighting. You can highlight your favorite passages in yellow, orange, blue or pink, which is especially helpful for students. 

A single charge gives you an impressive eight-week battery life, even with constant reading. The Kindle Colorsoft is waterproof, so you can read anywhere, whether it's in the bath, by the pool or at the beach. 

Just like other Kindles, there are no ads, social media, notifications or other distracting apps that'll pull you away from reading. Easily adjust the display from white to amber, depending on the time of day, and relax knowing your Kindle is waterproof. 

Whether you're a student or a working professional, a Kindle Scribe can help you stay on top of your to-do list by allowing you to markup documents and books so you can return to passages or leave reminders. Plus, the Active Canvas feature does a lot of the work for you. You can write anywhere, and Active Canvas will ensure your notes fit in the margins. 

With no distracting notifications or social media apps, you can focus on reading and writing. The Kindle Scribe also has a slightly larger screen than other models, at 10.2 inches. One drawback is that the screen remains black-and-white. The note-taking battery lasts about three weeks, compared with 12 weeks for reading.

Your child will have 16 GB of storage, which can hold thousands of books, and there are no distracting apps or social media. Fully charged, the Kindle lasts up to six weeks, and the black-and-white display helps reduce eye strain.
