Once I'd worked it out - which was after the problems were public and therefore the price had utterly cratered - they were by far the cheapest storage per Gb available at the time (think "by a factor of two").
I would not have let a normal business user near one, but the developers I was supporting were most pleased about their larger than expected scratch disks for test databases and intermediate compilation artifacts.
Everything breaks. Things that at least break predictably make me happier than the alternative.
So if you only formatted them (filesystem wise) out to capacity-2Gb they were a really cheap option at the time.
