Sony Reader PRS-T2 ( red)
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 ( special offers)
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.
Sony Reader Wi-Fi PRS-T1WC ( white)
While there's no compelling reason to buy it over the Kindle Touch, the Sony Reader Wi-Fi is a very solid e-reader.
Pricing not available
Kobo eReader Touch Edition ( silver)
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.
Barnes & Noble Nook Simple Touch Reader ( Wi-Fi)
The new touch-screen Nook is a major advancement over its predecessor and offers some real advantages over the 2010 Kindle.
Archos 70 ( 8GB)
The Archos 70 offers more horsepower and features than any other tablet under $300, but its limitations make it more of a toy than a tool.
Sony Reader Daily Edition PRS-950SC ( silver)
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.
Barnes & Noble Nook Color
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.
