The newest way to read has never been cheaper. Amazon is offering refurbished Kindle Paperwhites at a rock-bottom $79.
One of my biggest worries about e-readers when they were first hitting the scene was battery life. That's a big reason why I can fully recommend the Kindle Paperwhite.
It lasts for weeks on a single charge and you can read it almost anywhere inside or out, in low light to bright sunlight. One thing to keep in mind is that the Kindle Paperwhite is not a tablet. It's a dedicated e-reader that's black and white.
