The 'visual graph', from a tweet sent by All Things D's John Paczkowski, shows the reasoning behind Apple's laser like focus on Samsung. Just looking at the images would probably have you believe that Samsung was guilty of copying Apple's design. But you would need to know the whole story. The first touchscreen handset from Samsung's camp was the F700. Despite the uncanny resemblance to the Apple iPhone, the Samsung F700 featured a side-sliding QWERTY keyboard unlike Apple's handset. More importantly, the F700 was introduced just one month after the Apple iPhone. Some feel this is too close to the announcement of Apple's device for the Korean based manufacturer to have taken its cue from the iPhone.
Of course, the Samsung F700 isn't the issue of the current Apple-Samsung patent war, but we wouldn't be surprised if in Apple's mind, it is the first example of Samsung copying the look and feel of the Apple iPhone.
