On July 30, UNIX System veteran Sun Microsystems (NASDAQ:SUNW) released fourth-quarter earnings for the period ended June 30.

  • Management had hoped to reach a 4% operating margin this quarter, and floated past that mark with ease.
  • The overall margin uptrend continued to roll on, except when it came to the cash flow take. Large investments in infrastructure severely cut down the free cash flow, but that's not always such a bad thing.
