Mostly thickness...
Type I are the thinnest, most commonly seen on old memory cards. These are the ones that take up a single slot, but are constant height from side to side (no bump).
Type II are thicker, but still single slot. These are probably the most common.
Type III take up two slots, but with only a single connector. Most commonly seen are PCMCIA hard drives, but some modems and/or network cards use the Type III format in order to use a regular modem/ethernet jack with no dongle (Xircom RealPort).

Then there are 16-bit and 32-bit versions... both available in Type II and Type III cards. Also, there's the CardBus version, a PCI bus. For reference,

16-bit cards are PCMCIA or PC Card cards and use a miniaturized ISA bus.
32-bit cards are called CardBus and use the PCI bus. Any ThinkPad with a Pentium or later CPU should have CardBus slots.
Newer ThinkPads (T43 and later for example) also come with an ExpressCard slot, which uses the PCI Express bus.
