The Korean Herald reports that the Samsung Galaxy Tab has sold over 600,000 units in the month since its launch.  The Tab launched first on T-Mobile in the U.S. twelve days ago on November 10th.

That likely makes it the fastest selling Android Tablet on the market.  It also gives Samsung some credibility in its assertion that it would sell 1 million units by the end of the year.

“We believe tablet PCs will take over a bigger portion of the market next year,” Samsung’s mobile division head Shin Jong-kyun said at the IFA gadget expo in Berlin in September. “For this year, we’re projecting to sell up to 1 million units.”

Apple sold 1 million iPads in the first month of its launch, strictly in the U.S (though many of them got sent overseas).  It had not been able to keep up with demand for the first half year of its sales (now over 7.5 million units and 95% of the market according to Strategy Analytics) but is now expanding its reach.

Apple plans on launching the iPad in Korea in the coming weeks for instance.  The Tab has sold over 30,000 units in Korea but as BGR notes, there are reportedly 40,000 people on the waiting list for iPads.
