I can't afford a new camera right now, even though my current one is over a decade old, and I would really like a new one. My phone is also several years old and I can't afford to replace it on a whim either.

I make a fraction of what a typical IC in silicon valley might, and I'm not what you'd categorise as "rich" by any means. Middle class, more like.

My point is that I've seen people that only fly first-class put phones in plastic cases.
