S4 here. Nice phone but with the S5 coming out in a few weeks I'd hold off. I mean the S4 is great but why bother buying a phone that is getting replaced.
I'm no help but I am a "free agent" too. I am not sure I am going to get a new phone right now though. I have a Droid Razr and I don't really see anything out there that makes me want to get a new phone.
My only concern is that my battery life is getting shorter(less than a day now) so I may be forced to get a phone at some point. I looked at the Galaxy's but they are too big for me. I would like something no larger than iPhone size.
I really like the swipe to text feature so that knocks the iPhone out. So it looks like my options right now are phones very similar to what I already have.
I alway thought the Galaxies were comically large. Then I traded my old iPhone for one. I got used to the size very quickly, in fact, I grew to like the size. Hated the phone, but liked the size. Now that I have an iPhone again, I wish it was the size of a Galaxy.
