Lenovo's notebooks span the entire spectrum, offering low-cost models such as the G530, netbooks such as the IdeaPad Y530, and high-end models such as the ThinkPad W700. Today, we're taking a closer look at Lenovo's newest offering, the ThinkPad T400s, a thin and light model that's designed to give users a blend of portability, performance, and energy-efficiency.

The T400s incorporates many features from Lenovo's best selling notebook, the T400, and combines it with the some of the traits of the ThinkPad X300, which is part of Lenovo's lightest line.

In addition to being Lenovo's lightest T Series model, the company boasts that the T400s is 22% lighter and 17% thinner than Dell's E6400 and 22% lighter and 30% thinner than HP's 6930P notebook. As you should expect though, the portability and performance of the ThinkPad T400s comes at a higher price than everyday notebooks that aren't quite as portable.
