Samsung has shipped 5 million units of its Galaxy Note hybrid device, the South Korean electronics giant said.
The Note was announced last year by the company and hit AT&T stores last month with the intention of trailblazing a new market, as the device is larger than most smartphones but not quite as big as typical tablets.
The device, which comes with a stylus called the "S Pen," comes with an 8 megapixel rear camera, can shoot in 1080p and has a 5.3-inch touchscreen with 1280x800 pixel resolution. The Note runs Android's Gingerbread OS.
"It combines core on-the-go benefits of various mobile devices while maintaining smartphone portability, to create a whole new user experience," the company said in September.
