The technology on display proved more than capable of setting even the most jaded gizmo-fan drooling with envy. During a tour of NTT Docomo, one of Japan's prominent mobile operators, company representatives showed off a smartphone capable of projecting a clear image on a wall five feet away, along with ones equipped with 16.3-megapixel cameras and 3D screens. Intel and its Japanese hardware partners, including Toshiba, are pushing a line of thin "ultralight" notebooks. Sony's tablets, including the folding dual-screen "Tablet P," attracted considerable lines on the show floor.But Japan also wants to catch up with other global companies dominating the tech space, including Korean and Taiwanese entities such as Samsung and HTC. During an interview following his keynote, Yoshida acknowledged that Japanese companies need to catch up in the tablet space-and have the capability to do so."Our OEMs that manufacture PCs [have] also manufactured cell phones for many years," he said. "We have the ability to minimize. The combination of that is going to give them a unique advantage."
