In my opinion I think Apple should not complain too much on this copying issue, reason being, ideas at time are the same, the developers maybe went to the same school and as we know many developers do share ideas. I think Samsung should sue the speedy adjustments in the market of technology.
@hm, you raise a valid point but after reading this article to the end and checking a few of the links provided, am tempted to side with Apple over Samsung. It is an open fact that Apple were the pioneers of modern day Smartphones with the launch of the iPhone and a quick glance at the physical model of some of the latest Samsung gadgets reveals some very peculiar similarities to the former. So this may be an attempt by Apple to let the other competitors know that their patented features and applications are off-limits.
