E-Week: "Hewlett-Packard Co. on Thursday will announce that it earned a record-breaking $2.5 billion Linux-based revenue in fiscal 2003, with its Linux services and solutions business posting a 40 percent rise over fiscal 2002."

Wow -- that is a lot of money made from Linux. Unfortunately, H.P. isn't breaking out those revenue numbers, so I'm not sure how much came from "products" and how much came from "services." Still, big numbers.
