I've put some mileage on this bike now, not huge numbers, probably a couple hundred miles, including several night rides and a couple races at night.
So far everything is holding together fine, I recently thought I had a crack starting on the fork, but it appears to just be a scratch. I was cleaning it and didn't notice a metal shaving in the microfiber towel until the first swipe, but it's only 1 small scratch on the front of the fork.
Whenever I come across new people they always stop to check it out and ask questions, even the guys from a new local bike shop who were all riding similarly equiped Specialized, they even took a few photos to post.
I do think I need to true the wheels, but I started to one night and the spokes started to rotate with the nipple, so I stopped there until I felt more ambitious.
As far as riding, this thing is so fast up hills, never feels like I need more gear than the 32/42, I have run out of energy before I ran out of gear. Places I've stopped, even if I had a smaller gear I wouldn't have gone any further. Going downhill, sometimes gets interesting, I did a ride recently and followed a guy on a full suspension bike down a pretty gnarly section, I was quite a bit slower, but still followed down. It was mainly a poor call because there was a smoother line, but required commitment at the start as the lines were seperated by boulders or shrubbery (don't recall). The only on trail issue I've had with the bike happened a little after this on another section of rocky downhill. The bar clamp slipped causing the bar to rotate downwards, nothing broke, and I actually found a better bar position after this, so no harm no foul.
Couple things I've added have been titanium bolts pretty much everyplace except the seat clamp hardware.
Rotor bolts, caliper bolts, brake lever clamp, stem bolts, aluminum bottle cage bolts, uber light stem cap/bolt.
All told I think I spent about $70 on hardware and saved about 60 grams.
Here's a couple pics of those parts.

Brake Pad locator pins
I was suprised at how light the new ones were
