The keyboards should be able to withstand up to 11 fluid ounces of liquid through an integrated drainage system that "helps protect internal components," Acer said.
In addition to the tough keyboards, all of the laptops' chassis are said to meet durability standards used by the US military, specifically MIL-STD 810H and MIL-STD 810F for sand and dust.The company also announced the Chromebook 511 (starting at $350 in February) and Chromebook 512 (starting at $350 in January).Meanwhile, Acer's Chromebook 512 comes with a 12-inch screen at a 3:2 aspect ratio, rather than the wider 16:9 aspect ratio the other machines use.Acer said this feature is especially helpful in low-light situations.
It's the only new Chromebook featuring a screen reinforced with Gorilla Glass and Acer's antimicrobial coating, which fights bacteria with a silver-ion agent.
