To create a new standard it takes something that's not just a little bit different. It takes something that's really new and really captures people's imagination. And the Macintosh, of all the machines I've ever seen, is the only one that meets that standard.

Security guys break the Mac every single day. Every single day, they come out with a total exploit, your machine can be taken over totally.

Over 80% of the poor are people who have small plots of land and grow their own food and they don't grow enough to sell much into the marketplace. So they will be hit hard by the worst in climate. They really get hit hard starting in the 20-year time frame and thereafter.
