Seems a little soon I guess. But I suppose the same advances with the iPad retina display would carry over to 15" screens?

If you can't see a difference between image two and image three in my post, that's fine. Some of us don't have to jam our faces against the display to see it, though.Look, I quite understand that all of that is a non-issue. It's not apparent at all, even if I jam my face against both the iPhone 4 and the iPhone 3GS.
So even though there are exactly four times the pixels on the higher display, simply scaling a lower res image to the same size does not look the same. Physically it takes up the same amount of space, yes, but you reduce the space between pixels making the image sharper. Obviously some people will have a higher tolerance for being able to see the differences than others. Higher resolution is always better.
Depends how HiDPI mode works as I've stated. If the app thinks it's displaying on a 1440x900 screen, it will downscale your 1080p video to 900 lines. The system will then "pixel double" the result, so you'll still only have 900 lines of actual "pixels".
However, if the app is made aware of the scaling factor and can bypass it, providing an upscaled 1800p version of the video, then yes, you will get the entire quality.
Can you lower an LCD display from its native resolution and have a perfect 2 pixels to 1 ratio (e.g. 1440x900 down to 720x450), as opposed to trying to fit 1 pixel into the likes of 1.3 pixels width? Would all elements look as sharp as they would on a 15" 720x450 native display?

Ok I don't know why you are even saying this, I'm not disputing that retina displays will always be in their native resolution.. maybe you aren't understanding my english clearly.
No it wouldn't! The iPhone 4 will not automatically scale up images! A 300x300 image loaded on your iPhone 4 will not appear 600x600 on your iPhone 4 unless you zoom in.
I wasn't disputing that either..
If we stretch an image of 100x100 pixels to 200x200 pixels, how do you expect it to retain its clarity? Even if you are keeping it the same size due to increased PPI on a 15" display.
But the point is that the screen is the same size. 1 pixel is the same size as 4 pixels on the HiDPI screen. Unless you looked under a microscope at each individual pixel, then both images would look exactly the same.
Ahh, well, I can't imagine Apple not letting apps be aware of the available resolution, especially for photo editing. It'd be a mess to try get right though.
You know this 2880x1800 screen will look like a 1440x990 with sharper text, right?
Unless you can choose it to run in HiDPi or regular mode, though
Look, I understand what you're trying to say based on your experience that if you use an LCD monitor not at it's native resolution, things are blurry. That's because when you put say a 1024x780 monitor at 800x600, interpolation has to happen to map each pixel across a number of pixels that the LCD is "native" for. It's blurry because the interpolation is not happening at a harmonic frequency... but if you set the resolution to 512x390... it will actually look pretty good (obviously not as sharp as 1024x780), but this is the case with doubling the resolution in retina display. 1 pixel maps exactly to 4, so there isn't fractional interpolation. So it will look the same as the old non-"retina" display
Uh ? that makes no sense. I can plainly see the difference between a 960x640 image on the iPhone 4S and the 480x320 image on the 3GS. One is much sharper and detailed. That's plainly evident.
But what I'm saying is your pixel spacing theory is wack. Same 480x320 image blown up to 960x640 on the iPhone 4 looks the very same. It's not "sharper" than on a 3GS. Upscalers can't invent detail that isn't there in the original.
Why is the fact of this future MBP having yet another pixel density causing so much disscussion? A 800-600 photo will take up 1/4th the space on the new screen than it does on the current screen, same thing with any game that's stuck at a certain resolution. End of story.
STOP CONFUSING RETINA DISPLAY WITH HD RESOLUTION!
If this Macbook Pro gets a retina display, you still couldn't watch HD movies natively.
Your "desktop real estate" doesn't increase with this resolution bump - it simply gets crisper looks nicer.
I know that now - if you read the rest of the thread you'd see that I grasped that and acknowledged it all.
yes it does. if, for example, you have a bunch of 800x600 pixel photos you want to line up and looke at, the new display would allow you to fit 4 TIMES MORE of those photos onto your screen.
I consider that screen 'real estate'.
Eh? Don't think you understood this topic at all.
The 2880x1800 15" retina display will display content the same size was it would on a 1440x900 15" display. Everything will be far sharper though.
No, everything appears the exact same size as it does on the 15" 1440x900 display. Things are just as sharp.
Exact same idea as the 3GS -> iPhone 4. No more screen real estate, just double the resolution meaning sharper images/text.
Nope. take a photo (of a certain resolution, lets say 800x600) and put it on a 1440x900 15 inch macbook pro,
- and then next to it, put that same photo on a 15 inch macbook pro with the current 'hi rez' 1680x1050 15 inch MBP. That same photo will be smaller on the hi-rez MBP.
For that matter, put a current 15 inch MBP next to a current 17 inch MBP (i have both). On the 17-incher, which has a higher pixel density, EVERYTHING is smaller: The apple logo up in the left upper corner, 12-point fonts are smaller, etc.
I really don't understand why you think that if you qualdriple the pixel density that an 800x600 pixel photo would "look the same size".

You're right sorta. Basically the OS has the option to do either. Display the image natively (1 pixel of image to 1 pixel on screen mapping) or to scale it like the iPhone 4 will do. This will be the tricky part, what will Apple decide should be scaled and what should be kept native? If I'm looking at photos in iPhoto, it'll probably stay native, but looking at web pages where the text will be scaled proportionally but images will not will screw up the layout. So, the web page images will have to be scaled up... Right now, Mac OS X doesn't do any scaling for any images... everything is 1:1. With a "Retina" display, it seems like Mac OS will have to scale some things.
