The yet unannounced Samsung Nexus 10 tablet has already been leaked online, its manual at least, or so some quarters say. 
Why don’t you take a gander at the above and see for yourself? The manual arrived just a few days before Google has announced it, most possibly at an event that is happening on October 29th (which would be next Monday). The photos of the purported Samsung Nexus 10 manual do not reveal any more details apart from a sketch of the expected 10-inch tablet, including both front- and rear-facing cameras.
The Samsung Nexus 10 tablet will be larger than its Asus-manufactured Nexus 7 sibling though, where the former will come with a strip on its back. As to the kind of material used, it is most probably plastic, right where the camera is placed. The images are most probably the real deal, but we will only know for sure when the event rolls around next week. Do you think that the Nexus 10 will be able to give the iPad a run for its money?
