I did the just the opposite, short of owning an iPhone 6. I saw only ONE possible leak months ago that made me think "if this is what the new iPhone 6 looks like, I will happily wait in line for it". Then as the leaks showed what ultimately was the new 6, I became increasingly disappointed. The cutouts on the back looked hideous to me, and while not as bad as I thought in person, it still irks me a little. Sure, a case hides things like that but sometimes I like rocking my phone naked and I just didn't like it. The phones are definitely fast and perform great even with their lower RAM numbers than other offerings, and the screens no doubt look pretty damn good.
But what ultimately made me want to switch, other than the physical aspect of the phone, was being locked back into a standard iOS software that's not jail broken. I'm sure the JB community will find a kernel to hack in iOS 8, but I'm impatient and I didn't want to be stuck with a standard iPhone with a grid of icons like every other average iPhone, no control center toggles that I couldn't customize, ugly lock screen grabbers, limited airdrop file sizes, no night mode to darken the entire UI, no f.lux to adjust the screen hue at night (seriously once I got used to f.lux I didn't know how I've done without it, I LOVE it!), no customized animation speeds, that stupid parallax parallax effect, oh so much more on top of this.
Sooooooooo many of these aspects, and many, many more made me appreciate my device a lot more, as well as my iPad I'm typing on now with virtually all the same tweaks. But after spending time on Android devices in store, I realized I wanted a larger screen but had become bored with iOS. So far I'm happy I made the jump. I feel like I'll keep my iPhone as a dedicated music player for a bit, as I still love the phone. But I look at the screen and laugh as how I was able to put up with it all these years. But for the longest time, I thought I didn't need a bigger screen. And I guess I still don't, but I definitely like it.
Not gonna lie though, there's a chance I'll jump back when and if the new software is jail broken. A 64gb iPhone with a larger screen and many of the same UI tweaks as my iPhone 5 would be pretty freakin sweet. But for now, I think I'm good with my S5
