"Answering consumer's needs, Samsung has tied together the convenience of a large screen and full-size keyboard with superior battery life to make the mini-notebooks the ultimate internet and lifestyle accessory," he said.
"We believe the style and size of these products will meet consumer expectations, as they have in other markets," he added.
Together with GfK Samsung Australia undertook local research to determine what consumers want from a notebook with longer battery life at the top of the list.
