As a contractor I simply ask my employer for a USB drive and they ordered me one the next day. When I was a full-time employee at a different employer, not only did I have to use my own USB drive if I wanted to copy files from my workstation to a computer in a separate lab, I couldn't get a hard drive bigger than 40gigs in my workstation.
Simple point is, some companies actually care about making the jobs of their employees easier, and if that means supplying a $10 USB drive (that they can confiscate at any time) they make that effort. Most companies, however, spend as little as possible to aid their employees and don't understand why their productivety suffers. Their IT departments are also people who have simply undergone a multi-day training session, and are only there to look confused and package the broken components and ship them back to HP or Dell, they don't understand nor care that someone can copy sensitive information to a USB drive and walk out the door with it.
While it's interesting to see a product like this, the prohibitive cost and complexity will never see a vast market segment. Too many large companies simply care more about the bottom line than anything else.
