Why not an iWatch?

The biggest question from Tuesday's Apple keynote was obviously on why Apple decided to name its smartwatch the Apple Watch instead of the iWatch? To go along with the announcement Apple also named its payment system, the Apple Pay and not the iPay or something. Is this a coincidence or some trademark issue or something else? Here is an interesting take on this question, over at CNET

Apple’s not saying (on why the samrtwatch was named the Apple Watch and not the iWatch), but some analysts believe the Apple Watch and Apple Pay represent the Cupertino, Calif., company’s efforts to start a new era — one separate from Steve Jobs.

I don't agree with some of the other things in this post though, for example as to how the iPhone line has expanded under Tim Cook and that would not have happened under Steve Jobs. As I have stressed the point under a different post, iPhone line expanding is just a natural progression, like the MacBook or the iPod line expanded under Steve Jobs, once they had matured enough as products. To call this out and claim it is unique to Tim Cook's Apple does not make sense. 

Perhaps the biggest difference between Apple under Cook and Apple under Jobs has been the approach to devices. Jobs kept Apple’s product line trim, releasing one iPhone each year to fit all customers. But last year, Apple released new colorized iPhones alongside its premium 5S device, and this year it launched two models with different screen sizes, the 4.7-inch iPhone 6 and the 5.5-inch iPhone 6 Plus.
