You could get an inferiority complex about the televisions and appliances you own after attending this week's International Consumer Electronics Show. The way the industry's biggest names are tossing around the word "smart," you're left wondering whether any of the electronics gear you have has a high-enough IQ.Signs of the S-word in and around the Las Vegas Convention Center are everywhere: Panasonic trumpeting Smart Viera-branded televisions. Samsung proclaiming "The Future of Smart TV, Now." and LG Electronics asking, "How Smart Is Your 3D?"

But it's not just smart TVs that are on tap. Manufacturers are talking up washers, dryers, refrigerators, cameras and fitness devices with brains to be proud of. The remotes that control various electronics are meant to be smart, too. Not to mention, of course, tablets and smartphones. Even automakers are getting into the act.

And while the number of broadband-capable homes with smart TVs is gaining, the growth is not gangbusters, according to Brett Sappington, research director for Parks Associates. The percentage of broadband-capable homes with smart TVs connected to the Internet has risen from 8% in 2010 to 10% in 2011.
