Saratoga, Los Gatos, Monte Sereno, Menlo Park, Atherton. And, in general, typically more expensive than SF. Where do you think Larry Ellison, Mark Zuckerberg, Steve Jobs, Steve Wozniak, ... live/lived?

Of course, Robin Williams does live in SF, but that's not the same net worth ballpark.

I'll also add that San Jose is quite a bit larger in population than SF, so there are more people close to SJC than to SFO.

The BART option to SFO is nice although, last time I checked, it involved a change of trains at Millbrae.

Cheers.
