My (very limited) experience with peer programming: - It works very well if both of you are experiencing a language for the first time so you can both help each other with syntactical traps that you may find yourself in as well as other quirks that emerge with new languages. - It doesn't work as well for projects in which you both know how to code. Having another person watching you code over your shoulder is distracting and stressful, and often it would be more efficient for that second person to code simultaneously with you. However, these are only my experiences, and I'm sure they change from person to person. I'd recommend that everyone try it at least once - it may work for you, and you probably won't know until you try.
