I bought two of them but didn't realize they don't work in Windows (or the setup was beyond my willingness to tolerate). I don't normally use Linux for e-mail. They are still brand new in the original packaging.
They work with windows
When connecting the Crypto Stick to your computer Windows should prompt you to automatically search and install the appropriate device driver. Confirm all questions so that the USB smart card device driver is installed nearly automatically. Note that Windows Vista and above will fail to install an additional device driver for the smart card. This is okay and you can continue to use the Crypto Stick with most applications. Only if you intent to use the Crypto Stick for local Windows login, with Internet Explorer or Chrome web browser, you should install this minidriver.
In general GPG4Win is a recommendable package for Windows which contains GnuPG 2 and further usefull tools for encryption purposes (e.g. GpgOL plugin to use GnuPG and Crypto Stick with Outlook). Alternatively you can download and install GnuPG 1 binary.
I'll buy one if you still have it. Could use another one. Price?
These things are awesome for encrypting entire drives all sorts of functions
Ironkey is also a good hardware encrypted USB, works with windows easily but can store files on it. I have a few of those too
