Kobo this morning put itself back into contention in the e-reader space at BookExpo America by launching the eReader Touch Edition. Its new model has a namesake six-inch, infrared-based touchscreen that simplifies the interface even further with swipe and zoom gestures along with taps. The reader should also be an upgrade to the experience itself, getting both a faster, higher-contrast E Ink Pearl screen as well as a faster Freescale i.MX507 processor to speed screen redraws.
