Samsung on Wednesday issued a statement in response to a new round of rumors suggesting poor sell-through performance of its tablet devices. Samsung has reported several milestones for its Galaxy Tab Android tablet, which has now sold over 3 million units. Like other manufacturers, Samsung reports sell-in figures — sales into distribution — when detailing sales. On numerous occasions, Samsung’s 7-inch tablet has been accused of collecting dust on store shelves, as recurring rumors suggest the Galaxy Tab has very poor sell-through — sales to end users – performance. In response to this latest round of accusations, which caused Samsung stock to dip on Tuesday, Samsung spokesman James Chung issued a statement. “We don’t comment on market speculation but such talk is absolutely groundless,” said Chung. “Our tablet strategy is offering a broad product range with different sizes to support wider customer choice.” Samsung showed off two new Android tablets at CTIA Wireless on Tuesday: the Galaxy Tab 8.9 and the Galaxy Tab 10.1.
