Is there a Hardware Key Logger in your Public Library?

I came across an interesting article at Sophos. Key logger's have been found in public libraries in Manchester, England. This innocent looking USB key captures all keyboard activity. This means any email, banking account, social networking, or any other passwords entered at keyboard will be logged into this USB key. At an opportune time the perpetrator will sit down at the workstation and unsuspectingly remove the USB into his/her pocket. Know your computer hardware and prevent identity theft.
