For people who do not know what this is, it is basically a small device (matchbox) size where you can insert a sim card from either your mobile Internet dongle or 3G sim card and this device will broadcast the Internet using wifi. You can then connect your laptop (Mac/PC), iPad, iPod, PSP, etc via wifi to the Internet.
It runs off battery so it doesn't need to be plugged into a USB port to work. Although you can if you wanted the link below might explain it better.
