From your comments I understand that you can recommend either a Nexus 4 or a SGSIII. So if you pit these two against each other, which one will it be and why?
Concerning battery life, I may have exaggerated a bit, I was still under the impression I got from watching the Note II review, where the reviewer said it’s pretty much impossible to kill it in a day.
Of course, I know about custom ROMs, used to flash them all the time on my SGSII, but by tweaks I meant separate little tweaks I can install and use regardless of the ROM. i.e. I like some features in ROM X and some features in ROM Y, but as far as I know, the only way to combine these features is to look for ROM Z, which combines these features. Say on iOS I can have the standard multitasking tray, I can modify it to display more icons, I can install Auxo and have little previews, I can install Mission Control/Expose like app switcher. With notification center I can change the background pattern, can make it appear blurred and semi-transparent, can make it appear from under the home screen etc. all without the need to flash a custom ROM. Is this possible on Android too?
