Right now I am in the "non-S" upgrade cycle every two years - went from the IP4 to the IP5, and now I'm eligible to upgrade to the IP6/+ on December 29. The more I think about it, the more I'm considering holding off and waiting until next product cycle to upgrade (assuming the 6s comes out Sept. 2015). By the time December 28th comes around I will have waited 3.5 months from product launch date to my upgrade date. I've already waited this long...why not wait another 8.5 months and get the "S" version? I know you can play this "should I upgrade now or should I wait" game with every product, every year. This time around I'm just a little less compelled to upgrade. Going from the 4 to the 5 was a huge jump for me - the 5 was MUCH faster, and I personally liked the design of the 5 a lot better. After playing around with the 6 and 6+ in the store...I'm just not that psyched to upgrade right away. Don't get me wrong - they look great, they're fast, the screens are excellent. But I don't have a huge desire to upgrade to a device as big as the 6+. And the 6, while it would be a nice upgrade...just didn't do a lot for me. I really love the look of my black/slate iPhone 5. And the closest offering to that now is the "Space Grey". Also, my 5 still performs nicely - no speed issues or anything like that. In a nutshell, messing around with the 6/6+ just felt like "more of the same" I guess. So I'm thinking, why not wait until the 6s comes out and get on that upgrade cycle? That way I'll always have the fastest version of the most recent iPhone body design that is available. Also, I've never been a fan of buying "1st gen" products. The "S" versions always feel like the "completed" version of the originally released phone. However, my current IP5 could use an upgrade soon. The battery is weak, it doesn't like taking a charge from certain chargers without a little "fiddling", and there are a few small cracks on the back top/bottom glass pieces. I'm thinking of just buying a lightly used 5s. Has anyone else followed this train of thought and gone from being an "original release" to "S release" upgrader?
