If you think Bill Gates is ruthless then god help you if you ever compare this about Steve Jobs.
I actually admire Gates as he's done a hell of a lot and bringing up his kids in the right way. He's done more for charity than anyone else I know with his own money - if he'd have given his first 10 billion away, as the OP implies that he's wrong to keep it, then he probably wouldn't have been able to do as much as he has now.
Clive Sinclair has had a lot of press and was honoured (Sir) and will be remembered when he passes away.
I know we get carried away because we're Amiga fans but there has to be 'fair' in there for a debate.
