Ron Amadeo, writing for Android Police, thinks many of the design changes in the Galaxy S III — both hardware and software — were made in response to Apple’s trade dress infringement suit against Samsung:
So there you have it. A darn-near perfect explanation of the GSIII
design. Sure, it’s butt ugly, but it’s also 100% (well maybe 90%)
lawyer approved. An amorphous, unsymmetrical blob that doesn’t
come in black, with a non-permanent dock and non-square icons.
There’s no way Apple can add this design to their Samsung lawsuit.
It really does look a lot less like an iPhone than previous Galaxy S models.
