I've been trying out a Google Nexus 5 for the past few weeks and I'm not terribly impressed.
The bluetooth connection seems a bit better, and the screen is bigger, but usability wise, iOS7 is better.
I don't want most of the customizability (i.e., separate home screens/themes) and the keyboard is simply harder to use than iOS.
The whole OS feels laggy (still) even with almost-comparable hardware to the latest-get iPhone.
The only reason I want jailbreak is for something like F.lux/Twilight on iOS.
> keyboard harder to use
... it is 2013... get with the program and use Swype. It is impossible to go back.
Swype sucks if you use a lot of acronyms. Most of my work emails involve such. The iOS keyboard is really good at hunt/peck typing which is what's needed for such terse communications.
Swype causes keyboard popup delay of several hundred milliseconds on my N5. I stopped using it after 3 days.
Also what's with the default throb on key press in Android? Why would anyone find that useful?
Try out an AOSP based build (maybe the ROM from the google play edition?) on your phone. It's like night and day.
