Love that each reason has a small yet very illustrative figure but should the conclusion really be use fireworks? Based on my own experiences, once you have covered the very basics of a design by using pen and paper, you really need to stick to the end medium of your product, e.g. HTML/JS/CSS, and using as much real information as possible for the design. There's just too much room for self deception and errors when using less expressive mediums (screen shots, wireframes, etc). Even using something seemingly harmless as lorem ipsum can cause all kinds of problem with db data types, visual whitespace, etc.
