Creativity comes in many forms.
Engineering is itself an art and requires tremendous amounts of creativity to be at all successful.
You don't build a Boeing 777, a Porche 911, or a G4 Macintosh from a book of design standards - though such standards are often the foundation upon which you base your art. The art of engineering from conception and initial design through test and production is a creative act no less consuming than painting, sculpture, music, or literature. Most engineers are always looking for a faster, simpler, less time consuming solution to a problem - it makes one's life easier. It should come as no surprise that many have gravitated towards the PC since that's usually what they have at work. It's OK to suggest that many engineers are not creative like musicians and painters and poets, but we would not have the safe, clean, modern world we live in were it true of the engineer population at large.
