Well, I'm in Computers for over 20 years now but I really don't get it how to safely bring your Bitcoins on paper.
I had 0 experience in IT before discovering Bitcoin (other than simply being able to use a computer). It took me about 2 days to learn about secure offline storage. Make a bit more effort.
While it
is far from ideal that clients like bitcoin-qt automatically generate a new private/public key for the remainder of the output I find it hard to believe that anyone remotely interested in how to use a paper wallet could not account for this. Just use the paper wallet as a one time "coupon" and transfer the remainder of your funds in a new paper wallet. Problem solved and much more secure anyways because the used wallet's private key already had "contact" with the net.
What is there not to understand about a paper wallet? There is a public key to which you can transfer funds and a private key that allows you to spend.
The only difference to the digital form is that it is written on paper!
[edit] Oh, an it IS possible to specify the used paper wallet's address as the remainder output in some clients [/edit]
