Very interesting! Let me see if I fully understand your method. So the Thinkpad is your offline wallet and the USB thumb drive has the web site bitaddress. The UBS can be used in both the Thinkpad and your PC. This is genius!

Not sure if I agree with not encrypting. Although I do see your reasoning. I think I am going to go with actually printing multiple paper copies as well. As soon as I can things figured out for safe storage.
