So going by Apple's definition, a "Retina Display"
Does this apply at all distances?

if too detailed is function of distance, Why did jobs not mention that? it seems just like a marketing mumbo jumbo than anything, just like everything else with apple.
to help sell 50mil Apple has created an ecosystem of followers that are probably also their investors, that sell their product for them by giving them great reviews and losers go out and buy them. e.g. reviews.cnet.com/best-camera-phones/
the n8 is not mentioned.
also why does Nokia give you 64GB for $99 more and apple only 32GB. They are ripping you off.

Isn't Maemo 16-bit as well? AFAIK, Symbian isn't limited and uses 32-bit.

32 bit puts more stress on memory requirements. the frame buffer has to be twice as large, if n9 is 16bit and iphone 4 is 32 bit, then the display type is more important than pixel bit depth. cuz the n9 kicks iphone 4 in colors and brightness. in flesh. not to a microscope.

edit: n9 displays 16m colors thus it is 24 bit. 2^24= 16.777MILLION
iphone 4 is also 24bit www.displaymate.com/iPad_iPhone_ShootOut.htm

AFAIK 12,16,18, 24bit.

It is. The N900 for example has an 18bit screen I believe (6bit for each channel) but maemo sets it at 16bit since it's a more standard colour depth to deal with than 18bit. It's also quite an old phone now though.

The N9 does not beat it in brightness and If the N9 was 16bit it will not beat it in colour. It beats it in things like black levels. I believe the N9 is 24bit anyway according to its specs sheet so it's the same as the iPhone in that respect.

The memory requirements do increase but not to unacceptable levels since the resolution isn't that high. for 16bit it will be 0.781MB, 24bit is 1.17MB.

Edit: just saw your edit. yep N9 is 24bit.

yes but 1.17MB of ram that has to be close to the processor and fast comes at a cost.
but the n9 is so shiny. my wife has envy.

I guess bandwidth may become a problem and it certainly would make graphical effects more taxing. Your wife obviously has good taste.

The N9 display runs on 16 bits color depth. I don't know if the hardware would be capable of more, but the software is set to 16 bits.

I see, well that's too bad then. Don't have an N9 but I presume changing it would not be easy. Is anyone brave enough to change their X server config?

It's a bit disingenuous to have 16Million colours on the spec sheet if even the hardware was not capable. That would be asking for a lawsuit.

Apple got into all sorts of trouble for advertising "16 Million colours" in some of their mac screens.
