It goes beyond me 'not liking it'. I really think IPS is a superior screen technology for smartphones. I can list the reasons why, but at the end of the day it is my opinion only. However like I said before, just from reading comments, reviews, it appears most people concede that the One X screen is superior, and that uses an LCD 2.
With respect to your claim that Samsung uses a more expensive panel in their devices, that appears to be entirely
untrue.
"Economically, the use of AMOLEDs is more feasible for Apples iPhone line than for the iPad, and in fact may be slightly more affordable. According to Samsung, an LTPS AMOLED screen for its Galaxy S series costs $1.01 per cm2. A LTPS LCD used in an iPhone costs $1.02 per square cm2."
Ah, the battery life argument I keep hearing. Well I have two counters to that. One, battery life has never been an issue with me in my 4 years of owning an iPhone. In fact I find in my normal use with brightness at max that I rarely hit 50% by the time I get home unless I'm doing something especially taxing for long periods of time. (Like waiting in the airport for a flight and browsing the web for a few hours.) So I can't say I really need a device with more battery life. (Though of course I do welcome it.)
Second, and more importantly, this claim that the SIII has substantially better battery life compared to say the 4S appears to be
completely untrue. If anything, from all the reviews I've read, the SIII appears to be just about on par with the 4S. Furthermore the 4S appears to still beat it in things like browsing over wi-fi.
I did adjust the SIII in settings using the different modes and it did little to match the natural and accurate colors of an IPS display.
Like I've said to others, if you like your SIII display, great, but I think IPS is the superior display technology for smartphones. And forget this notion that you need to have one display next to another to see the difference. It's clear to me without doing so, and the difference is only exacerbated when you put the Amoled and IPS displays side by side.
