While it is true that the “SD” cards I’ve bought recently have actually been µSD cards with an adaptor so they can also fit into SD slots, it didn’t sound like that was what Chuck was asking. 

I have not seen an adaptor which will plug into a µSD slot and then allow me to plug my (visible-size) SD card into the adaptor.  I do totally agree that both the adaptor and the medium would be big enough to see in that case and that would be a good thing! However I have seen applications for a µSD card that would not mechanically work with the adaptor in question, due to packaging constraints, so I would not expect that adaptor (if it exists) to be a common item.
