Hey guys. Just received my 15" MBP this past monday but i'm returning it to apple cause the notebook vibrates incessantly whenever its on.
I'm just wondering if that has anything to do with the hard disk which i upped to 7200rpm. Maybe it's vibrating cause it's spinning too fast? Is there such thing? Anyone with a similar experience?
Another thing, i intend to install Windows 7 on it via bootcamp and partition the hard drive, but i have a concern. I have a friend who tells me that her mac is significantly slower ever since she partitioned her hard drive doing the exact same thing. This confuses me since i read online that using bootcamp instead of parallels to run 2 OS is better since u are required to reboot the mac in order to swap between OS and thus all the hardware is used for that selected OS. Where else when using parallels u running windows on mac and the hardware is shared thus making it slower. Is this true? What are your opinions? anyone used both and can tell me the difference? cause parallels i have to buy but bootcamp comes already preinstalled.
PS: when i use the word "slow" i am referring to the slow performance of the mac on BOTH leopard and windows OS.
Thanks in advance for all ur advice.

I read back then (I think even it was mentioned in this forum) that using 7200rpm HDD will cause slight vibration. If I'm not mistaken some vibrates more than the other depending on the brand.
Yes running bootcamp means resources are dedicated to the OS only and using parallel or VMWare (like my case) it will take a toll on the performance. I don't play games on Windows but I do know a lot of forummers advised to use bootcamp if you want to play Windows games instead of virtualization since it can be resource hog. I prefer VMware though instead of bootcamp since it save me the hassle of rebooting etc plus easy drag drop etc kinda thing. Short note though, running virtualization will not hog the resource too much if you are running for example Microsoft Office, Outlook etc but not for games, Photoshop etc kinda thing.
If you need the flexibility of running multi OS for example like FC, OpenSolaris etc then you will fully utilize your VMWare/Parallel but if need Windows and on budget constraint or the budget would be better off upgrading things and you don't mind rebooting, bootcamp is the way to go. This of course depends on what you need since if gaming then bootcamp is the only way to go
