When I was putting together my new bike (that I still haven't ridden), I had an option to go with disks. Due to the type of terrain that I ride and that I only ride singletrack, it just wasn't worth it to me. I'm happy with the feel of the Paul's brakes over with the possible XT disks that I could have used. I have only exploded two rims in my life, so unless I keep going through them it's just not worth it to me.
