So Apple never copied anyone either? Does the xerox GUI ring a bell? You know for a FACT? Do you understand the definition of fact? And Apple data mines too by the way, but I guess you like Apple so much you have no problem with that.
And really using an Android is like using your laptop. If you're smart about what you install on your phone, you won't have any problems. Remember all those OS X security issues a while back and the flashback trojan? I seem to remember everyone dismissing it as a non issue and telling people to use some common sense and not click on suspicious links or download suspicious files. Same concept here, except it's Samsung.
Original? You care about being original so much? Tell me what exactly is the brand of your car? Is it a Ford? Oh and best is subjective
Did they copy it or take the idea and make it better? Its a subtle difference but still a difference.
