Sony on Wednesday confirmed a long-expected update to its Reader e-book hardware. The Reader Wi-Fi, or PRS-T1, borrows much of its influence from the Xperia smartphone line, down to an 0.35-inch thickness and a lighter six-ounce weight dictated by a switch from aluminum to plastic. The design runs on a much newer, E Ink-made six-inch Pearl screen and now supports multi-touch for zoom as well as page turns through swipes.
