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's Nook Color is a capable color touch-screen e-book reader that offers much of the functionality of an Android tablet for half the price of an iPad.
Sony's flagship e-reader, the Daily Edition PRS-950, is a capable, well-designed e-reader that offers both Wi-Fi and 3G connectivity--but at $300, it's too expensive.
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.
The Nook Wi-Fi doesn't quite measure up to the Kindle in terms of design and overall performance, but it's a worthy alternative if you're looking for a more open e-reader that supports the EPUB format.
The Sony Reader Touch Edition PRS-650 is a slick e-book reader that's anchored by an impressive and easy-to-use touch interface, but the glaring omission of wireless connectivity will be a deal-killer for many--especially at this price.
Though the Kobo eReader Touch Edition doesn't quite measure up to the Nook Touch or the Kindle, it's a respectable and affordable touch-screen e-reader with a lot of pluses.
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.
While it's an improvement to the company's previous touch-screen model, Sony's Reader Touch Edition PRS-600 is saddled with a screen that's short on contrast and prone to glare--and it lacks the wireless convenience of Amazon's identically priced Kindle.
The new touch-screen Nook is a major advancement over its predecessor and offers some real advantages over the 2010 Kindle.
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.
If you can overlook the fact that it's missing wireless connectivity, the Sony PRS-350 is a very nice little e-reader that's anchored by an impressive and easy-to-use touch interface.
The feature set of the affordable Pandigital Novel looks good on paper, but this color e-book reader and multimedia device is hobbled by its extremely slow performance and unresponsive touch screen.
Though there's a lot to like about the Daily Edition, the dazzle of Sony's first e-reader to integrate cellular wireless connectivity is diminished by its lackluster screen and high price tag.
While there's no compelling reason to buy it over the Kindle Touch, the Sony Reader Wi-Fi is a very solid e-reader.
