USB thumb drives are inherently insecure without encryption. It does not 
matter if the file system is FATxxx or ext2. Although I always carry one 
with me, we are not permitted to use them at work. (And yes, the company 
hands them out free at marketing events).

But, with a Linux file system, then the drive is as secure as a local 
drive (Linux permissions).

My personal policy is that I use thumb drives maybe as sneaker net when 
needed or to copy WPA data (low risk for me since I would change the WPA 
if I lost the drive). I never use it for system passwordsor company 
confidential documents.
