Lenovo’s ThinkPad SL400 tops the chart with power and flexibility while costing under $1300. Meanwhile, HP gives Lenovo a run for its money with the HP Compaq 6530b. Without the power brick, the HP is lighter than the Lenovo (5.3 pounds versus the SL400′s 6.1 pounds); it’s cheaper, too ($1195 versus $1295). Both work well as business boxes that can go the distance: In our tests the SL400 lasted 5 hours, 8 minutes, and the 6530b ran for 4 hours, 22 minutes.
Sony’s VAIO VGN-NR485 helps you save cash, if you don’t mind its moderate performance. The system scored 75 in WorldBench 6, behind the SL400′s 84. The Sony is suitable for basic computing needs; and its 3-hour, 56-minute battery life and 200GB hard drive along with its price make this model a compelling deal
