I work for a company that takes agile development practices seriously, and I pair program all day, every day. I absolutely love it -- primarily for the reason you cite (I previously worked mostly solo as a freelancer or remote teammate)... having the direct accountability all the time makes me much more focused and productive. (fwiw, I am definitely an introvert, but a one-on-one situation is much easier for me than a group).

My company (World Wide Technology - Application Services) is hiring -- we have some physical offices across the U.S. and a few in other countries, as well as a growing "virtual office" team (which, while remote, is still in frequent communication and pairs remotely). Email me if you want to talk more or be put in touch with someone about applying (my email address is in my profile).
