You know, until last December, I only paid for a dumb phone. I liked my little Samsung slider thing with T-mobile, and only paid $25/mo for it. My job paid for a smartphone. Then my dad basically offered to help me buy an iPhone, so I could give up my work phone and all the drama that went with that. With T-mobile, there's no 'data plan' when you upgrade to a smartphone, unless you want to pay for super fast unlimited nonsense, which I don't. So I got the iPhone 5s and turned in my work phone for better work/life boundaries, and haven't looked back.
Things I miss:
-the little slider phone fit in my pants pocket (I am a lady with small lady pockets and the iPhone doesn't always fit)
-not caring if I dropped it
-no case needed
-simple to use
-good call reception, for the most part (I live in a basement apartment in a brick building, so that was always sketchy and we have a land line, too)
Neutral:
-I still only pay $25/mo. for the plan
Positive:
-having the features on the iPhone help me with work and life stuff all the time, from reminders to shared to-do lists with my husband, to not having to open up our laptop for simple things like checking the weather or managing money with Mint.com
-was especially nice that the iPhone worked on our trip to Europe, as we used WiFi and the Viber app to call home
-not carrying around a camera anymore--I use my iPhone for photos every day--I will probably never buy another digital camera, ever
-I got a FitBit for my birthday to help with weight and exercise management, and it's been awesome
Negative:
-It was expensive, and my DH got one, too - we won't be upgrading to the iPhone 6 anytime soon, that's for sure
-I have a scratch on the screen that bugs me
-I broke one case, so felt I had to buy another - the phone is so 'precious' that I don't dare not keep it in a case
-time suck of having internet constantly
