I know this is purely speculation, but does anyone think subsequent versions of the iPhone might be available in the colors and materials of the Watch? I'd love to see a stainless steel iPhone, even if it cost and weighed more.
Stainless steel is great for phones, unless you happen to need to make phone calls.
If Apple is going to crack the fashion market, as they appear to want to with the watch, they will need to train their customers to stop expecting that every product they make will match the colors of their other products. It's Apple, not Fisher-Price. A blue watch doesn't necessarily mean a blue phone is coming, and vice versa, nor should it by default just because.
