An opinion piece by tech writer David Gilbert looks at how CES might be losing some of its luster. "It's hard to know who the Consumer Electronics Show (CES) really benefits. A common perception is that CES is the place where all the major technology companies launch their latest and greatest gadgets. But this is simply not the case. Let's look at 2012 as an example. Last year's most talked about consumer technology products (in no particular order) were: the iPhone 5, iPad 3, iPad mini, Microsoft Surface, Samsung Galaxy S3, Google Nexus 7, Amazon Kindle Fire HD and the Wii U. How many were launched at CES 2012? None."
