The longest/hardest part of the job is jacking up each corner in turn and removing the wheel.

I agree with the recommend every 2 years, even more critical in more humid areas, less critical in place like Arizona.
A Pressure bleeder does make quick work of brake fluid flushing, but I've never taken the wheels off to do it, and most cars can be done without jacking them up, some are just too low. I like to work smart and jacking it up and removing the wheels is not always needed, especially on the X3, but that's just me, YMMV.
