Between this watch(whenever it fukking ships), new Apple TV, and possibly my 1st ever MacBook(not sure what version) Apple will have enough money from me for this year. Unless the S has something that blows me away, I'll be holding on to my 6+ for another year.
dog, there is no reason to upgrade your devices every year. I do a phone every other year when my contract ends and that works just fine. the ONLY time I wanted to upgrade early was when the iphone 5 came out and that was cuz the iphone 5 FINALLY introduced LTE service which is a must have if you're on sprint.
in my household, we got a lot of apple stuff this year as well. I bought my first MBP and the wife won the macbook air from her job and an ipad mini which she gave to me. me and the wife are gonna be getting phones this year as well cuz both will be 2 years old. and I'm thinking about getting apple tv, cuz my tv recently updated the youtube app on my tv and it works terribly now.
however, if I had the iphone 6+, I'd be rocking with that for another year.
