Ubuntu does something similar, but since they work on many things they let you decide how to split things up. What's interesting to me is that they show a cost comparision at the bottom, such as $5 being the same as the cost of a pint of beer. This really helps the user realize something like "I buy a pint at the bar without thinking, why can't I give the same amount to software I use every day?" http://www.ubuntu.com/download/desktop/contribute/?version=14.04.4&architecture=amd64 http://www.ubuntu.com/download/desktop/contribute/?version=1...
