The only PCMCIA cards I ever used were flash memory (direct flash and SATA drives), modems, and Ethernet adapters, and I only had them because I was writing drivers. (At the time laptops were expensive and not every employee had one.) Built-in modems, docking stations, and serial-port (sub-d9) zipdrives eventually did away with PCMCIA cards. Thankfully, because they were a terrible form factor and took a ton of space inside a crammed laptop.
