But there's a point where the "copying" that we as consumers like and benefit from crosses a line and becomes a shameless "knock-off" that we as consumers truly do not benefit from.
It's not at all clear that Samsung has crossed that line, but the line exists none-the-less and we as consumers benefit from there being a legal process to determine when the line has been crossed and penalties for those who cross it.
And in recognizing that we need such a line and a legal system to determine whether it's been crossed, we must allow that fuzzy cases such as these are inevitable. No matter how we might reform the system.
