No offense man, but I think you may be over reacting a little. And that's coming from one of the guys who broke a frame.
Since you asked - I've never locked out my suspension. I don't really see it as a viable way to do things, because I don't like stopping to change settings on stuff I can't reach from the seat, and I don't like the way the leaver on the rear shock sticks out when it's locked. I'm also a pretty big guy, with my pack on ready to ride, I suspect 220-225 is a realistic range. Yes, I wear a heavy pack, a gallon of water, a tube, a pump, a hand saw...no, I won't stop and change settings, yes I will stop and clear a fallen tree (if it doesn't make the trail more fun). As such, I run about 235 PSI in the rear shock. No, I don't jump my bike. Yes, I do bunny hop, pump, and ride some fairly large (as in bottom out the suspension large) G-outs.
Here's the bottom line. If I didn't like the bike, or it didn't have a great warranty, I wouldn't keep it. But (and keep in mind, I've owned a lot of bikes, and ridden even more) this bike is maybe the best bike I've ever ridden - for what I do. And that includes some wunderbikes that I couldn't by a frame on for what I paid for this bike. Don't sweat the problems that have been had. Tons of these bikes have been sold. What you see posted here is likely a very, very small percentage of what's been produced, and most if it likely by pretty rowdy or hard core riders that are putting a lot of miles on their bikes, or people who experienced failures doing less because of real production problems.
Either way, my advice is stop worrying, ride the crap out of it, and take advantage of the warranty if it breaks. When it does, do what I did. Say thank you for the new frame, get back on it, and ride the crap out of it some more.
