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.
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.
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.
Kobo Glo ( black)
The Kobo Glo is an excellent Kindle alternative, especially for readers seeking EPUB compatibility and international options.
Amazon Kindle ( 2012, special offers)
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.
Sony Reader PRS-T2 ( white)
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.
Amazon Kindle Paperwhite 3G
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.
Barnes & Noble Nook Simple Touch with GlowLight
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.
Kobo Vox ( green)
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.
Amazon Kindle Touch ( with Special Offers, Wi-Fi)
The Kindle Touch is Amazon's best e-reader to date.
