"HDMI- and VGA-out ports cover higher- and lower-end video support. In addition, you get a fingerprint reader, a webcam, a four-pin FireWire port, a WWAN card, and GPS. The hard-drive bay is easy to unscrew, and popping in a replacement is equally effortless. Less pleasingly, the budget-minded Lenovo ThinkPad SL400 business laptop has a boxier, less-rigid (though still sturdy) case than most ThinkPads have.
Overall, the Lenovo ThinkPad SL400 is a sound business laptop. Although it doesn't pack the firepower of some high-end machines, it gets the job done handily. Its combination of performance and value places it near the top of our charts."
