Today was Bill Gates' last day at Microsoft, the billionaire will leave the software company he co-founded in 1975 to focus on his philanthropic organization.
He leaves Microsoft, which he co-founded with childhood friend Paul Allen in 1975, to focus on his philanthropic organization, the Bill & Melinda Gates Foundation, the world's largest charity, funded in part by his vast fortune.
At an employee event at Microsoft's scenic headquarters campus here, Gates joined Chief Executive Steve Ballmer on stage to deliver a short speech and field questions from employees.
"There won't be a day in my life when I won't be thinking about Microsoft, the great things that we're doing and wanting to help," said Gates, who wiped away tears as the group of employees rose to give him a standing ovation.
Ballmer, a Harvard University classmate who joined Microsoft at Gates' behest, got choked up as he tried to describe Gates' impact on the company and society at large.
"There's no way to say thanks to Bill. Bill's the founder. Bill's the leader," said Ballmer. "This is Bill's baby."
