San Francisco: Apple co-founder Steve Jobs has had an impact on the world which will last for generations, Microsoft boss Bill Gates said, adding that it had been "an insanely great honour" to know him.
"Steve and I first met nearly 30 years ago, and have been colleagues, competitors and friends over the course of more than half our lives," he said, adding that he was "truly saddened" to learn of his death.
"The world rarely sees someone who has had the profound impact Steve has had, the effects of which will be felt for many generations to come," he said in statement, cited on the Wall Street Journal website.
"For those of us lucky enough to get to work with him, it`s been an insanely great honour. I will miss Steve immensely," he added.
