Query: Perfect!

I have a MacBook Pro 15" 2.16 GHz Core 2 Duo from late 2006. After updating my operating system, my computer slowed down quite a bit. Took it in to the Genius Bar and they suggested that I add some memory to it, and specifically suggested the Crucial brand. So for under $30, I went from 1GB of RAM to 3GB of RAM. Installing it was easy - after I located a #00 screwdriver to remove the casing, I popped this sucker in, booted up, and was all set. Computer is flying now!
