a. Samsung's designs are really similar to Apple's designs. Yes, all cars have to have round wheels, but as Nokia has shown (N9?), it is absolutely possible to design a phone with the same level (or more) minimalism without copying the design DNA.
b. Look at an HTC phone. There's no way one can mistakenly think that it's an iPhone. Same with tablets; a Xoom (esp. Xoom2), an Iconia, or a Touchpad will never be confused with an iPad.
In fact, this STEALING (couldn't mince words here) goes much deeper. This was on the internets a few days back: http://www.reddit.com/tb/kr14a
Doesn't this seem like Samsung crossing the line?
