Just received the new Macbook Pro 17" with I7 option as well as the 7200rpm HD 500gb. The machine works great so far. However, there is a slight vibration I can feel on the aluminum in front of the keyboard and basically across the machine, though when I moved it from a glass table to a wooden desk it was much decreased. The machine is also much noisier than I thought it would be, though I did know when I went for the 7200 option that it might be noisier. Is this normal because of the HD or I7 chip? I can return the machine and exchange it, but the anti-glare screen seems ok with no pixel problems, etc., so I don't want to look for trouble without a benefit. Is it possible this is not the HD? (vibration and noise does seem to emanate from the left side-I believe it is a Seagate, ID starts with ST) Thanks for any advice.
