Best overall e-reader
Amazon Kindle Paperwhite (2013)
While the "all-new" Paperwhite may seem like an unspectacular upgrade on the surface, it's a clear improvement over the original Paperwhite and arguably the best e-reader currently available.
Best ad-free e-ink reader
Barnes & Noble Nook GlowLight
While it doesn't necessarily beat the Kindle Paperwhite, the $119 Nook GlowLight is an excellent e-reader that's strongly worth considering if you don't want to buy into the Amazon ecosystem.
Excellent touch-screen e-ink reader
Barnes & Noble Nook Simple Touch
The new touch-screen Nook is a major advancement over its predecessor and offers some real advantages over the 2010 Kindle.
