People get up in arms because other flagship devices that are $199 on contract usually sport a quad core CPU and 1080p display these days.
Ok. The screen is a high dpi 4.7" RGB OLED display.
The computational setup is NOT conventional at all; with the marriage between the krait 300 based cores and motos own dedicated cores for fixed tasks. This is an intelligent way of tackling the multitasking beast that is Android, and will allow for further elimination of IO chokes due to how certain schedulers handle data across four general purpose cores.
Not to mention, the GPU beats the s4 in most tests.
At worst, by the time it's out, it'll be on the upper mid range side of the tech scale. I bet however, performance will feel very much high end.
4.3 should only serve to further improve that.
