No, but unless it is at a VERY good price, I would pass.

You can get a GPS for right at $100 (Garmin eTrex or Meridian Sportrak), and throw in mapping software (Delorme Street Atlas) for another $50 if you shop around. This gives you the same thing, but you have the option of taking the GPS into the woods. Even without mapping capability, a basic GPS can still help you find your way back to base camp or find a geocache.

Keep in mind that some new laptops do NOT have a standard RS-232 serial port. If you have one of these, you will also need to include an extra $30 or so for a USB-to-RS-232 converter.
