IBM has unveiled the new T41 line of notebooks, safe for use by crash-test-dummies. It integrates circuitry that can measure acceleration. If you drop your notebook, the new ‘Active Protection System’ (APS) will detect the impact and immediately move the hard drive heads into the ‘park’ position to avoid damage to the data.
Of course, with a far drop, your keyboard and screen are probably useless, but the data on the hard drive is often more valuable than the laptop itself.
