Chromebooks are a big deal for schools because they're cheap and relatively easy to lock down. However, not just any Chromebook will do -- ideally, you want a laptop that can survive bumps and drops from less-than-careful students. Acer thinks it can handle that unforgiving audience, so it's launching two educational Chromebooks built to take pupil-inflicted punishment, the 15.6-inch C910 (shown up top) and 11.6-inch C740 (below). Both have shells that withstand up to 132 pounds of force, corners that handle falls from up to 18 inches high, and reinforced hinges that won't easily snap. The C740 even gets specially extended hinges to make sure it won't flop or twist in high-stress situations, such as a kid's backpack.
