Plextor PX-SP "shock-proof" external drives

We're always a little suspicious when a company releases a line of products labeled with terms like "ruggedized" or "shock-proof," especially when those items are packed into tiny packages. So, we're a little wary of Plextor's claims that the company's new PX-SP USB hard drives, which weigh in at less than 8 ounces, are shock-proof. However, according to the company, the drives -- which are available in capacities of 80GB and 120GB -- are protected by a "silicon jacket bumper," which allow users to carry them "anytime, anywhere." We'll reserve judgment for now, though we're eager to hear how these survive some real world "anytime, anywhere" tests involving drops, falls and the wheels of large military vehicles.
