Thin and light laptops serve as a bridge between netbooks and full-fledged laptops, offering a smooth blend of performance, portability and battery life. This segment was previously reserved for super-expensive laptops that tried to emphasize all of these features while offering superb design and build quality. Although some luxury systems will fit that description, nowadays you can get very decent alternatives from $700 and up.

The typical thin and light sports either a 12- or 13-inch display, Intel's Core i3 and i5 processors, 2GB to 4GB of RAM, and 120GB to 500GB of storage – via SSDs or HDDs. Dropping the optical drive for the sake of portability and using a low-voltage CPU alongside a long-lasting battery is also a popular trend in this category but not necessarily the norm.

Sony Vaio Z

Sony's latest Vaio ultraportable is a two-part system that comprises a very lightweight main unit and a separate attachment that will turn it into a powerful desktop replacement when docked. The new Vaio Z is easily one of the most interesting laptop designs we've seen in a while.

Weighing just 2.6 pounds with a thickness of 0.86 inches, it's thinner and lighter than Apple's MacBook Air, yet Sony still manages to pack in a full-voltage Intel Core i5 or i7 processor, 13.1-inch display, up to 8GB RAM and up to 512GB of SSD storage. Graphics are handled by Intel's integrated HD graphics 3000 solution, but when paired with the docking station you'll be able to tap into the power of a discrete AMD Radeon graphics card and connect up to four displays using the additional VGA and HDMI ports. Sony's US pricing kicks off just shy of $2,000 and skyrockets beyond $4,000 with higher-end configurations.

Apple MacBook Air

Apple refreshed its thin-and-light MacBook Air lineup in July, adding Thunderbolt and Intel's latest Sandy Bridge processors to the mix as well as backlit keyboards on all models. The 11-inch model is available in two configurations: one with a 1.6GHz Intel Core i5-2467M processor, 2GB of memory, 64GB of flash storage for a suggested retail price of $999, and one with double the RAM and flash storage for $1,199.

Meanwhile, the 13-inch MacBook Air models get a 1.7GHz Intel Core i7-2637M processor, 4GB of RAM, and either 128GB or 256GB of flash storage for $1,299 or $1,599, respectively. Configure to order options include a 1.8 GHz Core i7-2677M processor and additional flash storage, but unfortunately no discrete graphics, only the built-in HD 3000 from Intel. Both maintain the same beautiful, slim profile as their predecessors.
