Samsung’s Galaxy Tab may not be up for purchase in the US just yet, but the folks over at Samsung want to whet your appetite a little more by releasing an official video demonstration of what the tablet is capable of doing. Features such as voice and video calling, productivity tools, web browsing, Flash 10.1, HTML, and multimedia features were all demonstrated in the video. Of course, the big question is whether the Galaxy Tab will be able to seriously challenge the iPad, and we’re looking forward to a juicy battle between the two devices. Let’s not forget that a 10-inch version of the Galaxy Tab should be arriving in 2011 too. Video after the jump.
