I expect you COULD say that Fuji's aren't "reliable" if you're talking in terms of lifetimes.
All super light AL bikes are suspect but we haven't seen a lot of failures yet. That doesn't mean they won't occur but don't worry about your Fuji falling apart within it's warranty period.
My brother picked up a Newest frame somewhere and gave it to me. I built it up into a bike and it rides REALLY nice. As you can see from my .sig I have some pretty good bikes but the Fuji rides second best.
