The elephant in the room is that Samsung did, and is still shamelessly trying to make a carbon copy of the iPhone and the iPad. The similarities go beyond casual coincidences. Right from the charger to the packaging to the layout to .. almost everything. It is so obvious they are doing that. It is no surprise Apple is going after them, and of course they should.
Please, for the love god, you and all people who think like this - take one second please to actually look at a Galaxy Nexus. It is so ridiculously unlike an iPhone. Samsung did do a pretty straight ripoff of the iPhone with the original Galaxy S. Since then their designs have deviated in major ways and really look completely different.
