Samsung’s latest Galaxy Tab model, the Galaxy Tab 8.9 was recently spotted in Russia and the folks of even got some hands-on time with the device and some accessories, like the keyboard dock you can see below.

Previously, the slate was leaked in Germany in some images also resulting from a hands-on experience. Back to the Russian hands-on, this time we can see the TouchWiz UI in action on the device, something that lacked form the Galaxy Tab 10.1 Limited Edition units given out for free at Google I/O 2011 last week.

Keep in mind that this is a mere prototype of the 8.9 inch tablet, so that explains the lag of the video playback. As far as the keyboard dock is concerned, this one makes the device a worthy rival for the ASUS Eee Pad Transformer and more on that experience you can learn from the following video.
