Samsung seems to be introducing a new tablet almost every week. Samsung has made a new designation for their tablet line with the Note series with the primary distinction being that the Note series will be coming with an S-Pen. What is the S-Pen and what is its capabilities? Version 1.0 lets you add a basic canvas, a pop-up for pen settings (opacity, line color and so on) as well as erase and un/redo. Sure, ICS might natively support stylus input, but as Samsung is keen to point out -- with its capacitive tip and configurable button -- a simple stylus this is not.
