I love this product! Its so light and easy to use, although as the previous reveiwer has said, it does lag a bit on the menu when searching through the books in your library but it soon catches you up :) You do definatly need the case with the external light on for reading in bed for example, but all e-book readers need this accessory from what ive heard from other users.
With an average of 350 books, (and PDF files are supported as well) you have more than enough memory to fit all your faves on :)
For just a simple, basic product that does the job this is perfect, and slips into your bag due to it being a 'pocket' version without taking up all the room!
Overall, a fab piece of kit, worth every penny :)
