another video - official samsung promo http://www.youtube.com/watch?v=hOX3H...feature=colike Go to the middle of it when they start talking about "ultimate multitasking" If you notice on the side bar (or bottom or top, you can change) one of the apps is youtube - this leads me to think that non samsung stock apps can also be part of split screen, although how well they work in a window may vary i really like being able to chat on im while referring to another document, or even the part where they do conferencing on the bottom while looking at documents up top, or even using smemo while on a call. This is seriously convenient. if this thing works well and robust for me its a killer feature no other phone offers. will wait till ppl provide more details of this feature but looks very promising.
