What is the nabi Dream Pen?

The nabi DreamTab comes with the Dream Pen, so what is this?

At its most basic, the Dream Pen is a stylus, but it is also more than that. The Dream Pen is a pressure sensitive digital stylus, rather than just being a simple plastic one. The Dream Pen will write just like a pen and it enables palm rejection (whereby resting your palm on the tablet doesn’t register when the stylus is being used, making it much more comfortable to use).

In particular, the Dream Pen is designed to be used with nabi’s Dream Pro Studio, and will allow children to write, draw, sketch and paint just like traditional tools – but without the mess that some of those can cause.
