While we all clamor and the 1020 (justifiably) but I have started wondering about the update to the 920, 925, 928. What do you imagine will come to the 930/940? What features/hardware do you want that fit within the 92X series?
well.. gdr3 is supposed to support quad cores chipsets and 1080p display.. but remember.. no 92x from the actualy line needs this quad core set, at least not at my 920, it never lags and never gets ''stuck''.. wp8 is very smooth and responsive..
phones screen are small, so the human eye can't tell much difference from 720p to 1080p display, some say you can't even see different due to the ''limit'' for dpi for human eye..
I would stay with 920, now that it has amber update, camera is pratically the same as in 925, while 920 still has 32gb against 16gb from the 925, and I prefer 920's design MUCH more than 925's.. it's up to you =)
