Apple and Samsung, two tech titans accusing each other of copying design features, return to court Monday to continue a multibillion-dollar legal war. Sam Gustin believes Apple's feud against Samsung amounts to "a proxy war" against Google and its Android operating system. Gustin tells us that for Apple it's more about principle, rather than money. The company nears $200 billion in annual revenue and sits on tens of billions in cash. The $2 billion suit remains a drop in the bucket. It's the long-term influence that's at stake.
