The Precision laptops are designed and marketed towards businesses and professionals (hence why they are on the business solutions section). Speaking generically; you can make a Precision match specs for an XPS but not the other way around. You're able to make a Precision laptop contain much higher specification components. The average computer user wouldn't need those high-end components so they are split into two separate lines and price points.
