"Silly" being the operative word here.
Not at all.
Some of you guys really don't understand how important design is.
For instance, I have a very distinctive modern retro look car, but if a Chinese company were to copy it and start selling it, all hell would break lose. Companies don't invest large amounts of money designing something and then marketing it at huge cost, for someone to come along and copy the bits they like and chuck it out at much less cost.
Companies need protection from each other to stop designs and inventions being ripped off.
What is so difficult to understand about that?
Samsung are going to have their arse handed to them over the Apple lawsuit, and not only are Apple going to be able to show that Samsung copies their designs, but that Samsung copies everyones design.
So forget the question of whether the icon has square or round edges, Samsung are going to be shown as a company that respects no one, let alone Apple.
What would be interesting is whether anyone else files a similar suit, especially Nokia, now that Apple have got started.
