I'm in the job market right now, so I'm wondering what are your experiences with using your Mac in the workplace? Previously I just used the PC supplied to me at work. Say you're in a medium-sized business that uses Windows and Office. Do you try to use your Mac at all? Bring your laptop and run OS X and/or Windows? Try to integrate your email with the office system or don't bother? Obviously you don't want to be a pain in the ass with IT to try to accommodate you. If you're trying to be the lone Mac user, it might not be worth it. My job would likely involve some internet research and writing. As I'm sure we all can agree, I can be more productive using my Mac but if I had to I can use Windows.
