A software license thread and I'm not involved yet? :O
I think everything that needs to be said in this discussion is already out there. However, to piggyback on what Trash has to say, read the "transfer of license" section in your EULA. If you transfer the media, license, and supporting documents, you give up your right to use the software and need to get rid of any additional copies you may have. This not only counts backups, but also whatever you may have installed. If you transfer the license, your copies are now the ones which are illegal. The guy who buys your software has the license now.
Think of it as transferring a house to someone. You give the new owner the right to live in that house, pass him your property deed, and turn over all keys and related materials. If you keep a key and use it, you break into his house, which is no longer yours. The key should be destroyed or transferred.
