The Barnes & Noble GlowLight 4 is a great e-reader for the budget-conscious. It's less expensive than other 3rd-party e-readers, like those offered by Kobo and Amazon.
The Nook e-reader has come a long way since it was first released nearly 5 years ago, but many consider it to be significantly less intense than some of the other devices on the market and is not as long-lasting.
It can be carried easily and packs a much smaller size than many competing models. The GlowLight 4 is much smaller and lighter than its predecessor, which makes it easy to carry around with you.
The Allwinner B300 is powering the Nook. It has 2GB of RAM and 29GB of storage. 5GB is available for sideloading and the remainder is for storing ebooks, which seems like a lot given that this device doesn't have an SD card.
The Nook's 1,400mAh battery is designed to last a long while without being recharged. B&N doesn't think that's accurate, but my week's worth of data suggests this may not be the case.
A smaller, more pocketable and more efficient ebook reader that comes with an even sharper panel. The GlowLight 4 is worth upgrading from any of the GlowLight 3 models.
