In Pragmatic Thinking and Learning: Refactor Your Wetware, Andy Hunt recommends using pen and paper to use your right brain and free your creative mind. When using a computer, you will concentrate on the details, not the complete user experience.
Another drawback of using a computer: if you show your design to the client, he also will concentrate on the details (“can you change the shade of this red button? It’s TOO red.”). Showing a hand-drawn design will let him imagine how the final product will look. This can be a double-edged sword, so you better know what the customer is expecting before using one of these techniques.
