Even if you don't use the immersive reading feature, it's really nice to be able to switch back & forth from reading to listening. It's nice to be able to start reading right from the sentence where you left off listening to the audiobook. Storyteller is a great e-reader and audiobook player regardless of if you use the immersive reading.

Also, it's just fun to have the audio narration as you read. I typically set the speed to like 2.5x when doing readaloud.
