This week marks the annual orgy of PR excess known as the Consumer Electronics Show. More than 150,000 (mostly male) visitors, many sporting T-shirts with mysterious acronyms like “4K in HD3D”, will alternate between 2 million square feet of exhibition space and the craps tables. Unfortunately for the 3,200 exhibitors, their marketing dollars will be squandered. Although I will predict a few likely trends, when it comes to CES, what happens in Vegas really does STAY in Vegas.
