Re: Rounded corners
Sorry but the rounded corners also applied to the shape of the device.
"The iPhone is radically different from the devices that preceded it. It has a
distinctive shape and appearance—a flat rectangular shape with rounded corners, a metallic edge,
a large display screen bordered at the top and bottom with substantial black segments, and a
selection of colorful square icons with rounded corners that mirror the rounded corners of the
iPhone itself, and which are the embodiment of Apple’s innovative iPhone user interface"

It is true that Samsung used rounded corners on their icons but those corners were much less rounded. Apple argued that many of the samsung icons looked like Apple's, eg the use of a handset at a 45 degree angle for the phone app and the use of a cog for the settings app. IIRC they also complained about the boxes that Samsung sold their devices in and the use of "rubber banding" when you scroll to the end of a page.
I suspect that Apple fell for their own marketing, they even told the court that they had invented touchscreen smartphones.
"Before the iPhone, cell phones were utilitarian devices with key pads for dialing and
small, passive display screens that did not allow for touch control."
