I'm hoping that having an Apple Watch will make it much more reasonable in the future to upgrade to the bigger plus size phones. The biggest factor for me choosing the iPhone 6 over the 6+ was that it was much smaller and could fit in my pocket at the gym. With the capabilities of the watch I won't have this excuse anymore. I think that it will be much more reasonable in the future to have a bigger phone because we wil be able to have a lot of the same features that drew us to a smaller phone on the watch.... But only time will tell.
