confident enough to believe he could change the world, and talented enough to do it," said President

Barack Obama in a statement posted on the White House blog. " By making computers personal and

putting the Internet in our pockets, he made the information revolution (信息革命) not only accessible,

but fun. The world has lost a visionary (远见者). And there may be no greater tribute to Steve's success

than the fact that much of the world learned of his passing on a device he invented."
