I have it and i almost feel no envy
BUT, is not the processor comparison that worries me, but the software additions that Microsoft puts only on the new devices; think about living images, which worked well on the 925 with a particular version of nokia camera beta. I only hope that they will keep pushing back the features even on the "old" hardware like they did before (the lumia 520 got double tap to wake, for example) of course with the obvious hardware limitations, the 925 will never have motion sensing due to the lack of sensor core, but i really hope they'll bring dynamic flash.
