I think Apple is in a tough spot here. I tend to be a fanboy that buys everything Apple, but in this case, maybe not. My reason is that I don't want to pay big bucks for a beautiful stainless steel watch, only to have it be obsolete in a year.
What I think Apple should do is have either a trade-up program, or a guts replacement program. Because it will be relatively cheap to replace whatever the next gen electronics are, but the quality materials, or stainless steel and sapphire, etc. are the things that are both expensive and enduring. Why not let us keep that investment?
So that makes me only want to buy the sport model at the lowest possible price, if at all, until Apple explains how they are going to fit Moore's Law in to a Luxury Watch!!!
