I've seen a *lot* of Big Agnes mattresses in the bin at REI Gear Sales, all with patches. Also a handful of NeoAirs and a few of other brands.

I'm still using my original NeoAir every month like clockwork, and loaning it out some of the time... not sure what to make of all the folks who've punctured them. I stopped babying it a long time ago - used to be hypervigilant about not getting anything with corners close to it, but a few months ago I actually slept on it all night with one of my trekking pole tips lodged under one side of it.

I've also noticed I don't blow it up as firm as others have with their air mattresses. Don't know if that makes a difference. I think it probably does.

I'd estimate 130+ nights on the NeoAir so far, if I count hammock usage and sleeping on the occasional floor with it.
