A study of 10,000 US computer users by customer satisfaction analyst Tempkin Group has once again ranked Apple as the top manufacturer for overall "computer experience" quality, which is defined as having excellent functionality, being accessible and generating the strongest positive emotions. This is the third year running that Apple has topped the list, but HP took second place -- losing by only two percentage points, and with a higher "functionality" rating than Apple. Sony and Lenovo were ranked least favorably of the 10 manufacturers rated.
