Re: Best of all it don't run windows
You're correct, mea culpa, that should of course have been Gates' (possessive plural of Gates, i.e Bill and Melinda) not Gate's. I also made a couple of other typos, too. Ah well.
I was finished, but then I was asked a question, and gave an answer.
Anyway, my original point was merely that Bill Gates isn't going to lose sleep over the lack of Windows on the Pi Zero, as OP had suggested he might. I stand by that. Mine was clearly a comment about how he spends his time (objective), rather than his motives (subjective).
In any case, what is altruism? If one considers the wellbeing of one's children and grandchildren as being 'selfish' (survival of one's genes and all that), then acting to reduce disease and increase education globally is also selfish. It's just not stupid selfish.
