I've had a PSP-1000, 2000, and now a PSPgo and I have never used custom firmware. I don't believe in pirating games and I don't really care for emulators, so there has never been a good reason for CFW.
Bethesda's Todd Howard "if install base really mattered, we'd all make board games, because there are a lot of tables."
