The whole world is littered with stuff, only idiots want to buy. In fact, 90% percent of all products do make such an impression to me. iPad 2 is one of the more harmless examples.
If somebody now buys an $400 iPad 2 (with a $480 iPad Air and $230 Nexus 7 available), they're just an idiot. Don't try to justify it, that's just the way it is.
