For those with "experienced iPod Touch users", I want to ask a simple question. I currently live in Japan, and it's close to getting one. When I saw the engraving option, I thought I might give it a try. However, what if I have those weird light leak, clicking sound in video, mushy home button, loose volume and lock buttons, and so forth? Would Apple genius replace my iPod Touch 4G with the brand new one without engraving (I wouldn't mind if I can get it earlier), or will they order the new one with the same engravings?
