What I like about Kindles is that for the most part they have something for everyone. Even the basic kindle has improvements. My first Kindle coming from Nook, was the PW1. It was blotchy but I loved it at the time. I didn't know it was blotchy, only later when I got the PW3
did I know how bad it was. Lol. They are always improving kindles no matter if it's the least expensive to the most expensive. Now you can have models that are waterproof with lots more storage and audio. Also with Voyage and Oasis buttons and with the latest Oasis comfort lights . They do add things their customers want eventually. People buy the one that works best for their needs. There is no best one, only the one you like best.
