I just made a switch over to a smart phone in August. Finally joined the world of being able to do more than just make phone calls on a phone!

I got an S4. I can't really compare to anything else, since this is my first smart phone, but I LOVE it. It did take me a little bit to get used to it, but nothing worse than just getting used to a new phone period. I actually find it much easier to use and easier to learn than the "dumb phone" I have for work (no idea what model it is, but it's a flip phone!). I love all the features and apps it has. I find it pretty easy to use and fairly intuitive (now that I'm used to it, and I'm no technological genius either - I'm the kind of person that plays around with it until I either break it or figure it out! lol). I can do a lot with all the apps available (including play games, who knew! lol). Now that I have internet included into my plan, I can also better conduct my personal business while on the go. Not sure how much that helps you, or what it is you are looking for in a phone, so just basically telling you my experience. Like I said, I'm still very new to smartphones, and don't really have anything to compare to.
