Among high-end laptops with quad-core Core i7 CPUs and discrete graphics, the Dell XPS 15 cleans up in battery life, running for 4 hours and 41 minutes in our video playback battery drain test. That previously mentioned high-powered Maingear 15-inch ran for 2 hours less. Of course, you have to exclude the Retina MacBook Pro for this comparison to work -- Apple's quad-core Core i7 15-inch laptop ran for more than 6 hours.

Dell offers a different level of warranty support with its XPS laptops than you'll find in less expensive Inspiron models. This Premium Protection Package, as Dell calls it, includes in-home service, accidental damage protection, and LoJack service, all for one year. A separate phone support line is set aside for XPS systems. Upgrading this package to three years of coverage costs $299.

Dell's high-end XPS line has gone through many different designs over the years, but the current look is the best to date, and fits well with the overall theme of a high-end laptop that mixes productivity with premium materials and construction. Still, this Core i7 configuration is very expensive at $1,699, and if you're more interested in the internals than the chassis, there are less expensive ways to get similar performance.
