Some years back, the popular line was “I have yet to hear what’s so special about the Apple iPhone, except that Apple has sold a lot of them.”
I am genuinely open to minded about those reasons. Apple has a reputation of putting some functionality in different products that other Apple products don’t have in order to not cannibalize each product line by allowing consumers to “have it all” in one product (some products have better screens, others have power, yet others have USB ports, but none have all features that customers want). I am therefore expecting the watch to have something that the iphone doesn’t have. I have yet to hear of one even though I would expect that working out with an apple watch is easier than with an Iphone. If someone can make a major purchase for that small a period of time (even though a cheap tiny mp3 player could do the same), then by all means the watch would make sense.
