I flew into SFO recently and got a BART to Milbrae (a few minutes, regular) and from there a Caltrain towards San Jose to Mountain View. From an outsiders perspective (living in London) if you live/work near one of the Caltrain stations I guess it's not too bad. The Caltrain feels slowish (and looks like something out of Mad Max), but does the job. You better be sure you have some way of getting from the Caltrain station to wherever you want to go on the other end though. I thought I'd walk to my hotel as it didn't look too far on the map but was actually a 1h30 walk!
