Entropy on a USB stick

If you care about security then you care about encryption. If you care about encryption then you know how important it is to have access to a good entropy source. (Or you should know. Not many people talk about entropy. I guess that it's something not very exciting to talk about.) Perhaps there are other similar devices and this is old news to some, but I was pleasantly surprised to learn that entropy is now available for little money, on a humble USB key:

The Entropy Key is a small, unobtrusive and easily installed USB stick that generates high-quality random numbers, or entropy, which can improve the performance, security and reliability of servers.
