I've been running mine as my main commuter for 15 months now. I haven't had any issues since my wheel replacement mentioned above that happened about a month after I bought it. Still shifts nice, and I haven't had to adjust the SRAM deraileurs since I bought it. I've adjusted the brakes a couple times, but that's normal due to pad wear. Also had two flats, which can't really be blamed on the bike.
I haven't treated it overly rough, but I haven't babied it either. I'm still a clydesdale, and reguarly load the rack down with stuff. My commute each way includes a ride across a couple of bumpy fields, a curb hop, plus a mess of train tracks. Zero issues.
Perhaps my bike is the anomaly. I guess I'm fine with that seeing as it's mine.
