The people I recommend the iPhone 4S for are the ones who are already in the Mac world, because it's so compatible, and people who are just scared of computers altogether and don't want to use them. The iPhone is the least frightening thing. For that kind of person who is scared of complexity, well, here's a phone that is simple to use and does what you need it to do.

I sold my most valuable possession, but I knew that because I worked at Hewlett Packard, I could buy the next model calculator the very next month for a lower price than I sold the older one for!

I wanted to be a fifth grade teacher because my teacher was so important to me and was giving me the education that was going to take me through life and through this world.

I just was non-political and didn't see myself as a person who could push people around, make their decision, you know, and tell them how lousy their work was.

I went and I started teaching computers to young kids, to fifth graders at first, later to sixth, seventh, eighth and ninth graders. I also started teaching teachers. And that was back in the days when we'd wire up the labs ourselves and crimp on the Ethernet connectors and then we would.

Don't worry that you can't seem to come up with sure billion dollar winners at first. Just do projects for yourself for fun. You'll get better and better.
