So, we knew the Galaxy Tab 10.1 was coming, but it looks like some shoppers eagerly anticipating the tablet's arrival will go home empty handed today. We just received word from a Samsung rep that there have been "shipping delays to some stores in certain regions." They went on to say, "We expect most retail locations to have inventory by tomorrow while supplies last." That's all we have at the moment, but we'll keep you posted as soon as we know more.
