We always thought about iPad Mini, iPad, and even Mac taking calls... But what if the iWatch becomes the new "phone/text/siri" tool and the iPhone becomes more of a media oriented dual device bridging the gap of the current setup and creating new categories within the gaps of the current categories? What I mean looks something like this: Size -----> ----- iPhone ----- iPadM ----- MacBookAir iWatch ----- iPhone6 ----- iPadPro ----- MacBookRetina Assuming the iWatch could one day make calls independently somehow with a new change in rules at phone companies allowing you to have a 3G enabled or sim-less phone add on thing to have two or more devices share a phone number, now you would have two categories of device and the iWatch truly being on the go with calls, NFC and Siri. So with the new setup the iWatch would do more of the things iPhone used to do and the new iPhone phablet does more of the things the iPad Mini might do, and for the full on pure tablet experience you can jump to a 13inch iPad Pro lol as they bridge the gap between MacBookAir and iPad. Since the dawn of touch screen technology we have been moving to making screen devices of every size and it looks like this: iWatch ----- iPod Nano ----- iPhone3.5/4/4.7/5.5 ----- iPad Mini ----- iPad ----- MBPAir11 ----- iPad Pro ----- MBA/P13 ----- MBP15 ----- (RIP 17inch MBP) ----- iMac 21/27 ------ Mac with 27inch Monitor or higher ----- Mac with HD Projector What if we shift it around at the bottom and redefine the categories a bit in a way that is even more effective or useful. Or Maybe just having more options to decide how we like to use combinations of devices in the Apple line up. It would be a cool idea but I don't know if it would be possible without having the iPhone as a base for the watch to connect from.
