Best of CES 2009(2)

January 16, 2009 9:50 am | Analog Devices, Inc. | Product Releases | Comments

The International Consumer Electronics Show 2009 didn’t exhibit a great deal of innovation. There were product announcements aplenty, as always at CES. But everything, from the keynotes to the exhibition floor, seemed very low-key (another victim of our lousy economy). Nonetheless, with 2,700 exhibitors catering to over 130,000 attendees, some products and/or technologies are bound to distinguish themselves.
