Matt,
Ungrounded receptacles are still made for situations where there is an existing ungrounded receptacle needing replacement. Instead of replacing the receptacle with a GFCI, you can use one of these. However... they are sold at "home centers" and the last time I looked, El Cheapo outlets from the big bin were about 40ยข, while these cost over $1.50. It's likely that the NEMA 5-15 outlets are used with nothing connected to the ground, instead of using these 1-15's
