The TravelMate Spin B3 notebooks are reliable devices designed around the needs of K-12 schoolchildren. They feature advanced processors, giving students all the power they need for classroom work, and comply with the MIL-STD 810G military standard, meaning that they\'re strong enough to survive the bumps and spills that are part of daily student life. A pressure-resistant top cover, shock-absorbent rubber bumper and reinforced corners all add to the durability of the devices. The notebooks can also get students through the entire school day on a single charge.
