Sigh, here comes my attempt to misinterpret you again.
Please bless us with your wisdom.
Regardless of what, LCD is dying and OLED is the future.
LCD has receive it's fair share of technological advancement in recent years with Sharp's IGZO tech squeezes the very last drop of what's left in LCD tech. May i say, LCD is in it's best possible shape right now.

OLED on the other hand, is still in infancy stage. It was Koreans who starts pushing the tech out of the door as soon as they can even when the tech is not fully matured. The best OLED out there are only having quantum efficiency of 19% to 20%. But even with that low emission efficiency, the power consumption matches the BEST LCD tech out there. With even a slight bump in that quantum efficiency, OLED will eat LCD for lunch without a blink in power consumption.

OLED turns on and off individual pixel but i guess you already knows that LCD backlit module needs to stay ON all the while throughout ENTIRE screen regardless of the LC alignment, right?
in junsheng world, man are making pentile panel to extend OLED lifespan.
on earth, samsung make pentile to save cost and increase output efficiency at the cost of unnatural coloring.
RGB arrangement CAN be done. As a matter of fact, the same idiot who came out with pentile scam scheme has later revised the arrangement to RGB and called it Super AMOLED Plus.

one fact that you gotten right here is blue polymer has shorter lifespan. However, the commercially available blue OLED already has LT50 of 14,000 hours which is good for 5 to 7 years on mobile device before the brightness hits 50% thus no longer making it much of a concern in mobile devices that has low screen-on time.
Another way of compensating the shorter lifespan of blue versus red/green OLED LT50 is to create MORE blue pixel, not putting in more long life green pixel like what samsung did.

RGBG pentile was a purely cost saving measurement by reducing subpixel. But why did green was chosen over blue/red? it was simply because human eyes are most sensitive to green color.
should we rather say, have you seen professional OLED?
Sony is a major endorser for OLED tech.
have you seen the best Sony LCD, aka thr HX series with every single sony's best tech thrown into it side by side with Sony XEL-1? How about Trimaster EL reference OLED monitor that is targeted at medical and broadcaster professional?
If you have the importunity to do so like me, you probably wont live in junsheng land talking junsheng junk anymore.

Back to mobile display and thickness wise, i hope you do know that LCD consist of 3 parts with backlit module, LC module and optical diffuser. With without the need of backlit and diffuser and the fabrication done directly on glass/polymer, OLED panel substrate alone is thinner than either 3 components in LCD. Have you actually work on these materials/device instead of googling around trying to make yourself smart?

OLED is still in infancy. Like one of the forumer mentioned, the poor absorption and reflection coefficiency as made OLED display a junk under direct sun light. But in its' infancy it has already live up to what the best of the best LCD has to offer. Samsung played a huge role in creating the impression that OLED sucks due to their inferior technique in pushing out affordable OLED panel asap. Regardless, OLED is still going to rule and heck Sony is going to be one of the major endorser.
on earth, modern electronics uses capacitive touch and "manipulate" pressure from amount of static charge. Synaptic palm guard for example. those stylus? has static tips to mimick touch and pressure. you can't glue a resistor film and capacitor film on top of each other. they will screw each other and make babies.
i get it, i get it, i finally get it now. 
It's like saying a plane is more fuel efficient than a car cause they can travel longer distance, travel faster and carry more people.
someone wanted to cross the street to convenient store behind the block, he/she would board a plane and not to drive a car.

Your advanced civilization practice that in your world?
I'm not a software person but for entertainment's sake, i briefly goes through linux kernel changelog just so i can misinterpret you.

What power management are we talking about here? new governor scheme? I've seen power management revision that allows hybrid sleep/hibernation in kernel 3.6 but that seems only beneficial for desktop environment and i can't seems to find major revision regarding power in 3.7 for RISC application. Care to shower your wisdom of what exactly is the new power management in 3.7 you're so excited about?

64bit? duh.

ARM support? multi rom? multi boot?
from my noob experience, kernel has never been a major blockage for custom android development. It's the proprietary driver and manufacturer skins that slows things down. Linux kernel 3.7 ARM support will not have significant impact on end user, even if you're power user. It only benefits developer on easier code writing.

I know there's some actual developer here in this thread hiding. mind to enlighten?
I googled but couldn't find any consistency whether Z has the barometer.
And as i said, the barometer has no meaningful application up to date since introduction in 2011.
