Don't really understand why it's ironic. Makes sense to me. What's so good about P90X? Weightlifting is king, regimented cardio = too high opportunity cost for me. It's good if you can't get to or don't like gyms. My friend did it for awhile and showed me a few workouts. They are intense and difficult. The learning curve is a little steep if you've never worked out before, but they include lots of bodyweight exercises so it can be very beneficial if you don't do them already. Pullups and dips will put a good bit of muscle on if you can't do them very well at first.
