xD cards are used in Olympus cameras; IIRC Fuji cameras as well.
Micro SD cards are pretty much the only format used in phones and MP3 players now. They usually come with an adapter to fit into any SD card reader.
“xD cards are used in Olympus cameras; IIRC Fuji cameras as well.”
Correct, but I believe they have changed to SD for more recent cameras.
I got a Fuji a few months back, with SD.
