I just hope people that are going crazy for the gold iPhone - especially those paying big money on eBay for them - actually want it because they like the color and not for the perceived rarity generated by the low availability. Those people will be disappointed in a few months when Apple ramps up the production and there will be gold iPhones everywhere.
If Apple really wanted to whip up a frenzy they could come out and announce that only X amount of gold phones will be produced and people will go even more insane for them, but they know better than that and will pump out gold phones as long as they sell until eventually they will be a dime a dozen.
Oh well, to each his own!
