With USB drives getting cheaper and cheaper, we've noticed that some businesses are providing press kits and some bands are releasing albums on flash drive. You can employ the same cool, 21st century promotional tactics on your own scale, whether you use it to hand out a design portfolio and resume or your kid's birthday invites (complete with an icon linked to your house on mapquest), with the Nexcopy USB Duplicator System.
This isn't exactly new technology, but it's the first time this technology has been so easy to use and so tightly packaged as to be suitable for home or small-business use.
It can copy up to 20 USB drives at one time. More info here.
