Here's a nice little rant from The Refugee over at Hospitalist With A View.
Here are some dictionary definitions of utility:
Used, serving, or working in several capacities as needed, especially:
Prepared to play any of the smaller theatrical roles on short notice: a utility cast member.
Capable of playing as a substitute in any of several positions: a utility infielder.
Designed for various often heavy-duty practical uses: a utility knife; a utility vehicle.
Raised or kept for the production of a farm product rather than for show or as pets: utility livestock.
Of the lowest U.S. Government grade: utility beef.
