Warranty

A few days ago, I noticed the down arrow on my laptop was getting a little fussy. Then, of course, I got in my email:

From: IBM4PCS
To: Dave Bacon
Subject: Dear Dave,
the warranty on your IBM ThinkPad T30 will expire soon.

I now suspect that IBM emailed my computer to get the down arrow key to act funny. What a great business model, no?
