Right. So the guy who invented the cell phone shouldn't have "copied" the guy who invented the cordless phone. Oh, and the guy who invented the touch screen phone shouldn't be able to make it because the guy who invented the cell phone (which can't exist because of the guy who made the cordless phone says "No") doesn't want someone to make a touchscreen phone.
That's stagnation and that's what you're promoting here. You're just splitting hairs by narrowing the focus to rounded corners, # of buttons, etc.
Truth be told, there are no original inventions here. Apple's products are evolutions of previous hardware created by others – let's not forget that.
Microsoft at least managed to try something completely different with Windows Phone, and I think it's a hell of a lot more innovative than what Samsung did.
Stagnation. That's what you get when people duplicate ideas instead of leading with their own.
