This is definitely noteworthy. I remember back in the early days when Microsoft and Gates were heavily criticized for being stingy. It's great to see those days are decades behind us. BBC:
Microsoft co-founder Paul Allen has said he will commit the majority of his estimated $13.5bn (£8.8bn) fortune to philanthropy after his death.
Mr Allen follows fellow co-founder Bill Gates in pledging billions of dollars to projects designed to help others.
He set up a charitable foundation 20 years ago that has given $400m. He has personally donated a further $600m.
Mr Allen founded technology giant Microsoft with Mr Gates in 1975 but left the company in 1983.
