G51 and G60 were launched around the same time, with similar goals in mind. Would it have satisfied you if ASUS made sure they changed the model numbers on everything while leaving it the same? That would actually add cost to the notebook.

The Optical drives on these things can be noisy, and they can be quited down by doing what your doing.

Interesting problem, only one we can really do anything about, if anything. How noticable is the difference, your brain has a tendency to cancel out redunant waves, delaying the playback timing of the left speaker by 3 ms would help a bit. Not sure that you can do this.
