I just completed the upgrade of my Macbook Pro with a 240GB SSD. There were only 29 screws to remove (and replace) in the process. For anyone interested in the gory details, here you go:

I was able to install OS X on the drive prior to taking the computer apart, and booting from the USB enclosure that I had the new drive in. I decided not to just "clone it" because this gives me the opportunity to clean a few things up. I will restore from the Time Machine backup things that are important!

It's so quiet that I was worried it wasn't on a few minutes ago.
