Add GPS to Notebooks
Start integrating GPS into all Dell Notebooks. This would be a big incentive to buy a Dell because people wouldn't have to buy external GPS devices. This could be an option that is bundled with Microsoft Streets and Trips, or some other GPS software.
Also, you could try addidng support for GPS into anti-theft software to literally track down a theif. Have the laptop report its location whenever it has a connection to the internet after it has been reported stolen.
