I live in Berlin and have just walked to work - I love it (even on a rainy day like today) - time to think.
Whilst Berlin is spread out I have found that you normally stick to your own "kiez" (neighbourhood). If you are lucky you'll be able to live and work in roughly the same area, and therefore walking (or cycling) is a great option.
As a previous commenter said, there are a number of shared car options available. I don't use these as I have no need, but they seem very good.
Also, the public transport within the city is very good.
There is, however, one danger of walking. It is very easy to find yourself stopping for a coffee or a beer on a sunny day!
