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.
With its more portable design, the Kobo Aura is a worthwhile -- albeit pricier -- Kindle Paperwhite alternative for EPUB fans who don't want to be tied to Amazon's proprietary ecosystem.
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.
The affordable Kobo Mini is a likable touch-screen e-ink e-reader that's too small for some and not quite small enough for others.
The Kobo Glo is an excellent Kindle alternative, especially for readers seeking EPUB compatibility and international options.
The $69 Amazon Kindle is an excellent no-frills e-book reader for anyone who’s willing to forgo a built-in light or a touch screen.
The Sony PRS-T2 is a perfectly good touch-screen e-reader whose only sin is that it doesn't have any competitive advantages over Amazon's and Barnes & Noble's e-readers.
With an excellent built-in light and Amazon's best-in-class e-book selection, the Kindle Paperwhite rises to the top of the e-reader pack.
The Nook Simple Touch with GlowLight sets the standard for e-ink e-readers going forward and is well worth the extra money if you do a lot of nighttime reading.
While it's relatively affordable, the Kobo Vox is a truly unexceptional Android tablet, with nothing to recommend it over the identically priced Kindle Fire.
