I'd say they last forever but we did manage to crack one this summer - a brand new one! Otherwise I replace only when lost.
We use Nalgenes as soon as our kids' teachers let them use water bottles without a straw (younger grades dislike that). The kids like them. We've cracked two. The recycled material in a specific green color seem to break when dropped on the edge of the bottom.
I don't see a whole lot of Nalgenes around, but my kids like them.
