Do you need a rugged laptop that can stand up to being dropped, shaken and doused with water — but you can’t afford the price tag? Acer’s answer is its touchscreen Chromebook 11 N7 , a hardened system that meets many of the Army’s rigorous MI-STD 810G requirements. And at $280 — one-tenth what even a typical Windows 10 rugged tablet costs — it’s a tough bargain to beat.
