I bought the Kingston 16GB USB as a  back-up tool for all my pictures and files from my computer. 16GB is plenty of space for the average computer user, I transferred roughly one thousand pictures and music files and still have 3GB of free space. I can't complain about the speed either, it's fast enough for my needs. The actual design of the flash drive is very sleek and modern looking with a convenient capless feature that prevents you from losing the cap. Even though you don't have to worry about the cap you could still end up losing the whole thing. The flash drive is so small that I think it would be very easy to misplace it. I would have preferred a slightly bigger size. Other than that it's fine. 

Question: How is the form factor?
