Lenovo must have struck a chord with schools looking for some rough-and-tumble ThinkPads, as it’s bringing out the ThinkPad X131e even while teachers are still drafting their course plans for the fall semester. The new model keeps that better-than-military ruggedness in an 11.6-inch laptop while freshening the choices of AMD E-series chips or their Intel-made Celeron and Core i3 challengers. Dolby Advanced Audio even gives the speakers boost when it’s not a matter of all work and no play. Educators, in turn, get the usual options for extended support or customizing the laptops with a little school pride. There’s a premium to pay for putting classrooms on the cutting edge, however: at $499, the new systems are $70 more costly than the launch price of the X130e portables they replace, which leaves quite a bit less money for notebooks of the paper variety.
