+Nowadays it's mere chance to find a USB Thumb Drive with less than 4GB storage.
+Though, you want a dedicated Drive to transport your password database, ssh keys and GPG keys.
+Those dont require more than a couple MB. So what to do with the remaining space?
+
+Scenarios:
+
+ - You visit friends, only have your keys with you and you have to check your mails, assist a colleague
+   in some network/ops emergency or just securely look up some important information.
+ - A family member calls, their HDD just died and you are asked to quickly help out on recovery.
+ 
+Boot into a safe environment, having all your credentials available in a secure manner.
+Have a bootable forensics toolbox around to quickly get going in a familiar setup.
+
+Solution: multi-boot!
