That was better than I thought it would be. The bit about manager's saying "I want a pony!" really resonates with me. My latest project caused me immense problems because I got one damn long shopping list from the client's head honcho, who finally said (as he left the room) "Oh, and it should look exactly like the one we have now because then we won't have to train people to use it." Now he keeps changing his mind. So the thing about "pixel-perfect mockups" had occurred to me as a way to avoid this in future, and it's nice to have it confirmed.
