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 ( blue)
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-T1BC ( black)
While there's no compelling reason to buy it over the Kindle Touch, the Sony Reader Wi-Fi is a very solid e-reader.
Iriver Story HD
The Iriver Story HD is a decent e-reader for fans of Google Books, but it's tough to recommend over its identically priced competitors, which offer touch screens and 3G.
Kobo eReader Touch Edition ( lavender)
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.
Kobo Wireless eReader ( WiFi, lilac)
Though the Kobo Wireless eReader is a serviceable e-book reader with built-in Wi-Fi, it's worth spending the extra money to get the Kindle or the Nook instead.
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.
