We don’t envy schools that have to go tablet shopping; many slates can’t survive roughhousing by playful kids, let alone impart some wisdom. Teachers will be glad to hear, then, that Samsung has fulfilled its promise of a classroom-ready tablet by releasing theGalaxy Tab 4 Education in the US. Hardware-wise, it boils down to a Galaxy Tab 4 10.1 with a rugged case — nothing truly special, but enough to survive a fall from a desk. The real highlight may be the software, which includes educational apps, books and videos alongside easy access to Google Play for Education.
