You know what you really make smartphones great? If Google and generally developers would really optimize the OS and apps to fully exploit the hardware.
Now, we have quad-core phones with apps that barely know how to use properly use 1 core and how to barely use 2 cores.
The closest thing to optimisation now is Windows Phone 7.8 and 8. Mostly all apps run on 1 GHz CPUs and 256 ram, and if not, on Dual-Core 1 GHz cpus and 512 ram. Everything!
