I did this with my old imac last year when a hard drive failed. I went to Best Buy and had the guy help me pick out the right sized hard drive and I paid them to install it. I didn't want to open up an imac. It was their standard ~$40 charge. Well worth it. For an additional $100 or so, they offered to then test it and reload the OS.... I knew I had good Time machine back ups at home and I passed on it. Took it home and loaded up my last back up. So, for you guys wanting to add a SSD to your macbook, why not let Best Buy Geek Squad do it. Just a thought.
