I finally upgraded my 15" Macbook Pro with an SSD. I removed the SuperDrive (since I rarely use it/it was broken/I have an external) and replaced it with a 120 GB OCZ Vertex 2 solid-state hard drive. I'm booting off the SSD and running all applications on it. However, I'm storing files such as movies, and large photo sets on my HDD. The drive is noticeably fast. I doubt I could go back to a standard HDD again. 

UPDATE: 
After using the SSD for a few months, I had issues of the drive not booting. It seems like this happened when I was using 80% of the drive's capacity. I reformatted the drive and reinstalled Snow Leopard. Unfortunately, I came across the same issue. I am in the process of getting the drive replaced.
