The commute can vary quite a bit, depending on where in Fremont you will be and where in Pleasanton you will be, as well as if there is an accident. Plan on 45min to one hour each way as a start. Do you have kids? What are you looking for in a place to live? Pleasanton is great, with a dynamic, charming downtown, good schools, but mostly older houses in your price range (1960's, 1970's mostly). If you want newer homes, then Dubin or San Ramon would be good choices, but for Dublin you will add about 10-15 minutes to your commute, and for San Ramon maybe 20-30. That said, there are a lot of people in San Ramon and Dublin that commute to Fremont and even places further south, because the homes are more affordable, and people like these communities. You can check out my website and get links to the cities mentioned to find out more about them, or provide more information about what you want.
