The tablet-computer market is like guerrilla warfare.
One huge army - Apple - dominates the land, while a ragtag group of insurgents keeps raiding and probing, hoping to find some opening it can exploit.
With Samsung's new Galaxy Note 10.1, the rebels have scored a small victory.
It's a tablet that does something that the iPad doesn't do, and it does it well.
This victory won't win the war, though.
