Sometimes referred to as ultraportable or ultrathin, the lightweight laptop is twice the size of a netbook, yet it still feels light and easy to carry. This category offers a perfect balance of performance and portability, especially for frequent flyers. These models are plenty fast for most types of work and have a mid-size screen that's comfortable to work on. Most even have built-in DVD burners, which netbooks do not. This category can be expensive if you order the biggest hard drive or fastest processor available.
