Someone (I think THG) just did an article about SSD, within it addressing this issue.
Basically, they leave pagefile on for anything less than 12GB of RAM.
So, leave in on the SSD. Wouldn't you want the fastest access to the file (if ever used)? Yes, it "could" degrade the performance over time, but you have 8GB of RAM, so it'll never get used...So use it, and don't fret over long term degradation.
