I've deciding I'm sticking with a smartphone. I was getting my taxes done this week, and having a smartphone really came in handy. I had to look a few tax forms up, which I didn't bring with me to the tax guy. It was really easy to be able to look up the documents on my phone, and saved me a trip home and back.
I am checking http://www.phonearena.com/ for upcoming phones. I would hate to buy a new phone and then have a brand new one come out a day later. I might see if I'm able to get the Galaxy S7 that is coming out on Friday. I still have a Galaxy S4 and it's held up pretty well.
I will not be switching to an iPhone mostly because of the ecosystem. Like I've mentioned before, I'm not impressed at all with Apple's cloud system/account syncing, and I've never had a problem with this with Google/Android.
I also may finally be giving up my unlimited data plan in an attempt to barter down the price of a new phone!
