Unlike the iPhone
, some handsets will pack it in when they hit the curb or floor from waist height (sorry, we just couldn't resist). Sony's "Liquid Cushion" patent application works by placing your device in a sealed chamber within a second perforated chamber filled with fluid, surrounded by the outer housing. Drop the handset, and the liquid will squeeze out of the perforated chamber and absorb some of the impact. Clever idea, but we're thinking if people are worrying about battery replacement
now, just wait til you have to deal with anti-shock goo.
