The Orizon was an upcoming 6-inch e-reader with a touch-screen display that used new "In-Cell touch capacitive sensing technology." It was billed as having smoother touch operation than Sony's PRS-600 Touch Edition e-reader, with no glare or contrast issues (we were impressed by a demo).
However, the Orizon never quite made it to stores, and Sony has now released its new PRS-350 and PRS-650, which use much-improved IR-based touch-screen technology. A few months ago, Bookeen showed "real" models of the Orizon on its blog
, so we expect to see the company displaying some new products again at CES 2011.
