    What are the practical uses for the thunderbolt cable and why should I need one?

    It is there to connect Thunderbolt equipped devices like external drives or hubs (though none are available yet) or other peripherals.

    It is like a USB or Firewire cable, you use a USB cable to connect a USB device to a USB port and you use a Firewire cable to connect a Firewire device to a Firewire port.

    it's a data connection, like USB, but much higher bandwidth.
    USB2 - 60 Mb/s
    USB3 - 625 Mb/s
    thunderbolt - 2500 MB/s

    it also carries more power and can be daisy chained through multiple devices without a hub.

    Unless you have a device that is specifically marketed as a thunderbolt peripheral and a machine with the corresponding port, you should ignore it. Thunderbolt cables share a port connector with mini displayport, yet thunderbolt cables will not connect to mini displayport or displayport devices. The port can be used for displayport displays, but you'd need to use a mini displayport to displayport cable, not a thunderbolt one.
