To put things in perspective, CEA's economist DuBravac noted that there might be 20,000 new products, including smartwatches, announced this week at CES, but not all will appear on physical or virtual store shelves later this year.
"Products come in two types at CES: Those that are feasible and those that are commercially viable," he said. "A lot of what you see is intended to show what's possible, perhaps in five to 10 years."
He added: "Early on, smartwatches need to connect to smartphones, but maybe someday smartwatches will even replace smartphones."
