Also another Apple iphone 5s user here. The 4s would take forever to upload updates. Also the fitbit app slowed it down and battery needed to be charged too frequently.
The 5s is not much more expensive per month. I text my daughter in Ireland on the unlimited texting plan. Flat fee per month. I use it for phone calls, fitbit app, the weather, emails etc. No point in getting an iphone 6/s. They were wanting a $1000 can a few months ago for one.
