This survey was in the field from April 27 to May 10, 2004. The results are based on answers from 8,250 PC Magazine subscribers. Scores are reported for vendors achieving at least 50 responses.

Note: A statistical t-test was used to calculate significant difference between a vendor's score and the industry average. This objective mathematical formula sometimes presents identical scores with different meaning. Scores are said to be average, better or worse than average, and significantly better or worse than average. Take the example of Dell and ABS's "overall rating" scores for all desktops. While readers give both companies an 8.1 score, the t-test indicates that statistically, Dell's score is significantly better than average, whereas we can report ABS's score to be only average.
