I consider patent wars a storm in a teapot... cheap moves to abuse the patent and legal system in order to inflict maximum damage to comepetition.
I think anyone who had a chance to use android and ios would say they are different...
again - why are they suing samsung? samsung is using android... because every phone that is not apple's is either android, wm or a feature phone. So what was samsung's fault exactly that it got sued? "we will sue you, because we can"?
That was a rhetorical question...
