A lot of big-name companies have downsized their presence at CES. Dell and Heweltt-Packard recently have been pulling back from the show, and neither will have a booth on the show floor this year. Similarly, Nokia confirmed last month that it had scaled back its presence for CES 2013. And some companies have even dropped out of the show completely; Microsoft said last year that the 2012 CES would be its last. Is CES losing its star power?
