If you're still using USB flash drives, and would like to pay £50 (USD $59) for a single 16GB stick, here's the designey solution for you. This is the Empty Memory Transparency USB stick:
Because your average USB flash drive looks like this on the inside…
…you might wonder how the heck they made this transparent. It isn't, it's a visual trick. Each unit is stainless steel, and the storage end of it has been polished to a mirror finish, giving the visual impression that it's transparent. (*Correction: Sharp-eyed readers have pointed out that the transparent portion is, in fact, transparent acrylic; it appears the chips have been shrunken and stowed inside the metal portion. Thanks to Damian, Dan and Scott for the spot.)
"Each design contains a physical emptiness in its sculptural form," the company writes, "giving the metaphor that you can fill the space with your own memory." I think the memory that would stick with me most, is that I spent ten times the price per gigabyte.
