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.
