I am in love with the concept of the Removable Storage USB Keychain (or Pen) Drives.
I have a 64 meg one right now that I do all kinds of wacky stuff on.
I export reg files that have all of my program prefferences and drive mappings and keep on the keychain.
I have this KICK ASS program installed to the drive called Password Manager XP. Its a realy good password management database. You can high light a record and hit a button to transfer the pw to the clipboard or you view it.
It stores the pw database encrypted with about 6 different algorythms all at one time. Including 3DES, Blowfish and RSA. Its only $18 so I bought it.
I also just put in an order for a 256meg keychain drive. Time to upgrade.
