They have talent. They have tenacity. And, they achieved this goal while protecting investments in research and development, aggressively managing cash balances, and gaining market share from competitors."

We also increased sales of our high-end UltraSPARC III processor-based products such as the Sun Fire 6800 and Sun Fire 15K mainframe replacement servers. These gains were augmented by strong market acceptance of our newest products such as the Sun Fire V480 4-way server in the low-end space and the Sun Fire 12K server in the high-end space. The Sun Fire 12K server has been particularly well received as it is taking sales from the competition while strengthening and enhancing sales of other Sun high-end products."
