I did this in Boston for a while and it was quite great. The bike went away for the winter, of course.

Public transit isn't as good as NYC or Chicago, but it's decent.
You clearly haven't been to Chicago recently. CTA has cut frequency drastically AND raised fares.
Or if you're fortunate enough to work somewhere that has a shuttle that's another option. Many of the big tech companies do now, thanks to Google's lead. Off the top of my head: Google, Facebook, Apple, Genentech (I actually knew someone who would take the Genentech bus to work even though they didn't work there. Guess they don't check)
Of the people I know who live in SF and work in the valley, I'd say roughly half drive, and half take the train or a shuttle.
I usually take Caltrain but sometimes drive.
