I work with my laptop in construction areas, and I always bump my computer or spill something on it. Is there some way to protect this thing?
You really touched on a big dilemma for mobile PCs. How does a device intended for use in the field protect itself from the dangers and foibles of real life? Drops, smacks, and spills are just some of the dangers that await mobile computers on job sites and remote locations-and yet, most laptop, notebook, and tablet PCs are quite fragile. For hardcore Navy SEALS types, Panasonic offers a line of shock, spill, vibration, and dust-resistant Toughbook notebooks that endure MIL-STD-810F testing (the latest and greatest military standards).
