Near the end of my 14-day return window I went into an Apple Store to see the different colours and was very close to doing the same. The orange aluminum is truly gorgeous in person, and I don't think photos do it justice at all. The only barrier was that they didn't have any non-Max ones in stock - if that were different, I'd probably be sitting here with a Cosmic Orange iPhone.
But I've also grown to be happy with the Deep Blue since then. I think especially in the right light it has a beauty of its own and it's at least a colour I know I'll be happy with for the next couple of years. I do worry the Cosmic Orange might still be a fad for me and when the novelty wears off I won't like it as much.
