Whether we want a computer which can think like a human is a separate question. The Turing tests is only concerned about whether we have such a computer.
Of course you can redefine the word "thinking" however you want, and state that a GameBoy can think according to your definition. That does not really teach us anything though. The point of the Turing test is we have no objective definition or measure of whether some entity "can think like a human" or not, so the best we can do is to test if it appears to think like humans. That is not saying anything about whether is is "good" or "bad" to think like a human. I am certainly happy that computers and machines in general does not think like humans!
