MultiMediaCards are MUCH easier to interface with - chip select, data in, data out, clock and ground. They're smaller than floppy disks (about the size of a postage stamp) and they store a lot more data. Once you get past the "Omigosh, look at all the commands!" stage, they really are easy to interface with. Here's a hint - you only need to use three commands: read_sector, write_sector and read_card_info. I can't remember their official names, but you get the idea - read and write memory sectors, plus a "how big is this card? what does it support?" command.
