Two very commonly overrated aspects that you just mentioned... 1080p and BlahBlah megapixels.
720p and 1080p are not easily discernible. I, a self-proclaimed videophile... someone who constantly gripes about picture quality... someone who constantly points out to friends and family how their color calibration on their TVs suck... someone who used to play FPS competitively on PCs... cannot even tell the difference between 720p and 1080p.
Unless of course you start showing me examples on ginormous screens.
Megapixels? What good is that 13 Megapixels when the 8mp on my 4S still takes better pictures than any Samsung out there?
3gb ram and 8 cores... okay, that deserves credit. The rest are just upgrades in numbers to make it feel substantial.
5S from 5: Jump to 64bit processing up from 32, though it's more for future purposes. Point being that it is setting a trend that the industry will definitely benefit from.
Further real tweaks to the camera and not just upping the megapixels. You know, tweaks that actually matter.
Noticeably improved graphics - always an underrated aspect that deserves more credit seeing as how the mobile phone market has completely dominated the hand-held gaming arena
M7 - Sounds real good on paper and is a big upgrade... utility remains to be determined
Nah... 5S had the bigger jump than the Note III. Note III is still cool AF though and I'm excited to play with both that and the 5S side-by-side.
I'm not so sure that the difference between 720p and 1080p isn't discernable. I can certainly notice the difference between the S3 Screen and the s4 Screen and the improvement with the note 3 over the note 4 will be even more significant, due to the size.
However, I can understand how there would be no point increasing the pixel density on a screen as small as the iphones.
