Perhaps they have a database of model numbers and the one that I provided is on the, "It's possible that it was sold new during the upgrade window," list. The only problem is I have no interest in upgrading the laptop -- I use it every day at work and don't want to change the OS -- and would prefer to install it on a different machine that I can use as a test bed. The confirmation that I got indicates the the upgrade has to be installed on the machine for which the upgrade was confirmed.
