Samsung expects to sell one million Galaxy Tab devices by the end of this year, the company said in a statement.
The Android-based Galaxy Tab, Samsung's first tablet PC, was launched in the UK this week and will be made available across the US from next week. The company had already launched the device in South Korea in October.
The device has so far received encouraging reviews from tech pundits and is being touted as the first actual competitor to Apple's iPad, which has dominated the fledgeling tablet PC market since its launch.
Encouraged by the success of the iPad, which sold 3.3 million units in the first three months of its launch, other tech giants, including RIM, HP and Lenovo, have been planning to launch their own tablet computers - but Samsung is the first to release a rival to the iPad.
Shin Jong-kyun, president of Samsung's mobile division said in a statement: “We are confident of [making] over 1m sales this year as consumer responses in Europe and Asia have been quite good.”
He added that the company was planning to launch a number of tablet devices in a variety of screen sizes in the future.
