Apple :: OS X 10.6 Experience On 64GB SSD

I have an older Samsung SLC RBX series 64GB SSD lying around. This was one of the very first generation SSDs to come out on the market. I was interested in installing this in my early 2009 15" MBP, and I wanted to ask how the experience of a limited hard drive (i.e. only 64GB) will be in Mac OS X. I am currently on a 500GB WD Scorpio Blue, and have about 50% used with various documents, music, etc. Obviously, I realize that I won't have the same functionality with a more limited hard drive. However, the speed improvement I think will be far worth the decrease in capacity, and I was hoping that someone with experience running Mac OS X on lower capacities drive could chime and let me know of some of the pros and cons.
