Samsung has sold more than 600,000 Galaxy Tab units worldwide in just a month of its launch, the Korea Herald reported on Tuesday.
The South Korean electronics maker's tablet computer, which runs on Google's Android operating system, is currently available in more than 30 countries, including the US, the UK and India.
"We believe tablet PCs will take over a bigger portion of the market next year," Samsung executive Shin Jong-kyun said recently, the Korea Times reported.
The company said it expects to sell one million units this year. In contrast, the Galaxy Tab's rival device iPad hit a million units in first 28 days of its launch.
The seven-inch tablet was launched in some European countries in mid-October in the US in mid-November.
