How not to remember customers

Today I received an email from Sony about buying a new Vaio computer. I bought one about 10 - 12 years ago when I was in college. Today Sony had a great pitch for me: "Be the best in class: Save on VAIO PC campus value packs." There might be a deal in there somewhere--but the fact that Sony still has me listed as a college student shows how poorly they manage their mailing list.

So how much does Sony care about me as a customer? Very little obviously.
