Copy or Creativity
I don't like Apple Inc.
They always played the poor underdog until they became a mean beast themselves. They became rich and powerfull with the help of all the app developers... and now screw them big.
That said... In the case of the IPhone design vs the Samsung Galaxy S I believe Samsung did a poor job and merely copied the IPhone design instead of being creative themselves. When I first saw the Galaxy S I first thought of it as a IPhone clone.
The IPad vs the Galaxy tablet however I see much less infringements (but still very little creativity from Samsung)
