I used to, but given not a single one of my SSD drives (I have 4 deployed in my house) has so much as balked once in a year of continuous deployment, I am cautiously optimistic.
I ran a 60GB SSD as my Windows machine's system drive (with pagefile) for four years before it started showing problems, and that machine saw a few hours use almost every day. It was >90-95% full for most of that time.
