Samsung's design flaw

Samsung is known to built thin, hardware devices for many years. But recently they have taken a step to be more design focused like Apple and came out with their latest Samsung Galaxy S3 phone. They claim the design to be inspired by nature.

But...what I do not understand is, why is the Home Button off center? I mean its really annoying. What happened to symmetry? They recently launched the Galaxy Note 2 and it doesn't have this problem.
