Whoever's idea it was to make a neon green phone should be fired.
Well, it was a key factor in bringing me back into the iPhone world. Sorry, but I don't think "this product isn't as popular, thus someone should be fired" is a good answer. Also, I think the 5C popularity will level out more over the holiday season and it'll prove a slightly better product for Apple than if they'd kept the 5 and dropped the price $100. It does two things:
1. It gets people like me who love the unique colours, and wanted something different, and didn't care as much about specs back into iPhone (I'd switched from an iPhone 4S to a Nexus 4).
2. It gets people who DON'T want a coloured phone but don't care about specs (business types, more serious, have the money) to buy up to a 5S instead of getting last year's model.
THAT, dear sir, is a win-win for Apple. A bright, pretty, coloured phone for the teenage mindset (not necessarily just teenagers, I bought one); and more differentiation between last year's model for the older crowd who may not buy up for specs but will to get a metal iPhone.
