USB Data Transfer Device
This is a very handy USB gadget. Its the USB Data Transfer device which enables you to copy data from one PC to another. Just plug it in the PCs you want to transfer and do as you copy your normal data on a HDD. But the only drawback I feel is that the cable length is just 4 feet. So can't be useful if the other PC is another room. The transfer speed is good which is around 25 MB/s. It is priced at $50 and is available at Think Geek.
