Author fails to see that iWatch is actually a single model, without any variation at all. Same OS and apps, same controls, same hardware. Counting straps as different models is really silly. And besides, not a lot of people are fans of metal bracelets.
Second - if we are speculating about how Steve would see iPhone 6 then saying that he would keep THAT design and only fiddle with diagonal is also silly. Steve would have imagined something way more efficient and pretty - no button maybe, maybe radically different materials for body (and solve stupid stripes vs. radio dilemma), maybe it would be a flip or slider, maybe... maybe... Definitely not just 0.2 difference in diag.
