We use it in my company all the time honestly. Do I use what I learned? No, I already knew how to run a project, all the PMP does is it says you know what the PMI calls those activities. But all the time we drop the PMP letters to get us in the door or shut out competition. "Yeah, but do they have a PMP? We do."
But I have to agree, if I wasn't consulting, there'd be little to no point.
