What would this change?
Samsung will lose one of their biggest customers. Apple will go to <insert company, probably in China>.
Samsung are one of just two companies in the world capable of manufacturing the panels used in the new iPad and (this is just an assumption) the upcoming iPhone 5. The other company's output can't match Apple's demands.
The threat of losing Apple more money than they would get from suing Samsung all the time would calm things down. Samsung can do just fine without producing Apple products, and it's also a matter of principle.
