Steve Jobs' legacy is one of continually, relentlessly building beautiful, useful things that anyone could use and love to use.
Because of his efforts, the tools that I use every day are the best possible tools. Celebrities can't buy a substantively better computer than the one I use every day. Heads of State can't own a better smartphone than than the one I use every day. That egalitarianism of technology is a wonderful legacy. It may have been the case without Steve Jobs' hand in it, but what he also brought was a craftsman's perspective. He didn't want to build adequate things. He wanted to build beautiful things.
I hope he continues to be an inspiration, because we'll not see his like for a long time.
