Eye-Friendly E-Books

Expect no glare from Sony's new reader.

After years of enduring eyestrain from illuminated displays, fans of eBooks can stop squinting. Electronic ink, or E Ink, has hit the mainstream, and manufacturers are launching affordable portable reading devices that use it.

Sony's Reader ($350; www.sony.com) is first out of the gate with its crisp 6-inch E Ink display, which delivers a high-contrast, paper-quality look with no glare.

The paperback-size device holds up to 80 titles; you can add a memory card if that's not enough. Amazon and Panasonic are said to have similar readers in the works, although they haven't issued details. One thing is sure: With the popularity of eBooks, Sony won't have this shelf to itself for long.
