The iPhone has fallen "somewhat behind" in terms of smartphone features, according to Apple co-founder Steve Wozniak. The comment emerged during Businessweek's Best Brand Awards. "I am proud that we have such loyal fans," he said. "But this loyalty is not given, the need to have the best products is always there. Currently we are in my opinion somewhat behind with features in the smartphone business. Others have caught up. Samsung is a big competitor. But precisely because they are currently making great products."
