Ask anyone leaving or entering the US (or, indeed, any of several countries who may choose to screen phones upon entry/exit) if it's niche. I'd also submit that the iPhone is hardly a luxury item. I know that's a relative term - feature phones are luxury items in some regions of the world - but it's no yacht or Maserati or other such "luxury" item. Many, in fact, got their iPhone for free.
