I was a bit concerned about opening my MacBook Pro and modifying it due to initial perceived difficulty and the possibility that it would affect my Apple Warranty, but it did not.
In fact, it was much, much easier to install and setup that I thought, and now my system screams! It went from an almost 3 minute boot time to just 47 seconds! So I purchased another older MacBook Pro for my wife, and am swapping out a BIGGER EXTREME 6G in this machine, and putting my 240GB in that one.
After using the drive for some time, I visited the Apple Store with questions about Mac OS X. They assisted me with my questions, replaced my power brick, and helped me configure some unique system settings - fully aware that I had opened my MacBook Pro and installed the Extreme 6G - no issues.
