iPhone 5S is available in Gold, and since iPhone leads the other i-products, we can expect to see more golden Apple products.
The next golden product from Apple is rumored to be an ultra-thin and golden iPad mini. I don't think we'll have to wait long for a golden iPad or iPod touch. Gold looks good. Gold is a classic.
It's time for covers to match the gold. Gold shouldn't need to be hidden inside a protecting cover. I think it's time for a cover that protects, but doesn't hide. Very thin glass that doesn't get scratched might be the fix. Or why not a scratch-resistant body and glass-plate to remove all need for protection? They're probably getting there.
