Serious high power applications are mostly IGBT and Thyristor. If you need to control a diesel-electric locomotive or an electric catapult for your 5th generation fighter aircraft, you're probably not using a MOSFET.
Last I looked (may be out of date) most PC power supplies used BJTs in the power output stage.
A lot of cheap flyback converters may still have a single high voltage BJT, for cost reasons. This is what you might find in a switching AC adapter of a few watts. CFL circuits generally use small high-voltage BJTs, and I would not be surprised to find LED lamps using a similar circuit. Those represent huge volumes of parts.
Almost all the low voltage stuff, and a great deal of the off-line switchmode stuff has migrated to (regicidal) MOSFETs in recent years.
So, it's kind of a dated observation, with, at best, only elements of truth in 2014. Le roi est mort, vive le roi !
