I am an active software developer and DBA, who looks at the code all day long, and I absolutely LOVE my new retina MacBook Pro with Windows 7 installed under Boot Camp!
A quick sidebar is that I am still confused when I read articles about the lack of NVIDIA driver availability and other issues posted in reviews even on prominent sites like Anandtech. I think they may have created their reviews before Apple started to officially ship these laptops... - i.e. I got my laptop on June 18th, used Boot Camp wizard to create USB with Win 7 Ultimate x64 with SP1 and installed it outright (after resolving a quick NTFS support issue using NTFS-3g under Lion) and have been happy ever since. There is a support folder created by Boot Camp that contains Boot Camp installer, which installs all of the drivers (including the supposedly missing NVIDIA driver) and everything is tip-top.
Now, back to the resolution, and the use of this laptop for development…
Out of the box you will get the maximum resolution (2880x1800) and Windows will apply 150% DPI scaling (actually it is 144 DPI as opposed to 92 DPI by default). And although you will marvel at the display, you will quickly realize that the text is still too small. I got a near perfect 20x20 and I still had to go up to 168% before I felt more or less comfortable. (Note that I tried 200%, 175% and some other values in-between, and although text gets bigger, many UI elements (even Windows / Office 2010) start mis-behaving, look pixelated, etc.) So, again, after some experimenting, I settled at 168%.
Once you settle in at whatever DPI you are most comfortable with, you will start setting up all of your apps – Office, Other browsers, RDP, Management Studio, Visual Studio, etc., and that is where it starts being a little challenging. Not all apps support high DPI (or non-"standard" DPI setting). While IE8 and MS Office 2010 handles everything reasonably well, other apps may require you to adjust compatibility setting and disable the effect of DPI, which makes them work right, but text is super tiny unless you go in and adjust default text size (which is what you will end up doing just about everywhere). So, get ready to Zoom like crazy, although many apps will remember and respect the zoom setting once you dial it in.
Quick note regarding other browsers - as of this commentary, I somewhat refrain from using Opera and Chrome, because I could not find a right Zoom combination that worked well for web page UI elements. Sure – the text is bigger – but layout breaks and things look weird enough for me to go to another browser. So far, I am happy with IE8, Firefox 14, even Safari, but not with Chrome or Opera.
Another side note is that unless you have other super hi-rez monitors, moving the application form MBP screen to a monitor with less than 25XX resolution will present a challenge (unless aforementioned compatibility setting is set, and even then you will need to reduce text / zoom out.) This is because even a "typical" hi-rez 1080p monitor (i.e. 1920 x 1080) will display your app like 680 x 480 when you move it from MBP display - not physically, but perceptually - blame your new retina display if you like...
But back to the retina display - the display itself is amazingly sharp and clear, and with a little effort you will get tremendous benefit (especially if you are a coder) as you get smaller, but much, much... much clearer text (so smaller text is no longer a problem), which means you can display a lot more code on the screen and your efficiency will improve significantly!
In closing, once you go retina, you cannot go back - a few hours working with it and you will not be able to use a typical laptop (or low-rez display), because everything will look pixelated and fuzzy.
That's all I have to say - thanks for reading.
Supported resolutions
Retina, Ratio 16:10
scaled, Ratio 16:10
- 1920 x 1200 pixels
- 1680 x 1050 pixels
- 1280 x 800 pixels
- 1024 x 640 pixels
According to the official tech specs by Apple.
How does the scaling work?
According to an article in AnandTech:
Selecting any of these options gives you the effective desktop resolution of the setting, but Apple actually renders the screen at a higher resolution and scales it to fit the 2880 x 1800 panel. As a result of this scaled rendering, there can be a performance and quality impact.
There is a new option to configure the resolution in the system settings. While you actually change the resolution, Apple only refers to the visual impact of the settings.
So basically changing the resolution offers:
- Large text, but much crisper.
- More space for visual content (and smaller text), but not as sharp.
- Something in-between (default retina).

Note:
Due to the imprecise definition of "retina display", this answer may seem confusing, because at the top Apple speaks of 2880x1800 as retina, but the picture suggest something different.

This is because of how Retina is implemented on these new systems. In the Mac OS (and iOS for that matter), resources are doubled in size, therefore each point is roughly the 4 pixels.
To the system though, it still reports the 1440x900 size, even though the actual pixel count is 2880x1800. The Mac OS knows how to handle this looking for @2X resources or using native code to render things at a higher resolution offscreen before painting to the screen.
While on Windows though, it is outright seeing the 1440x900. Since Windows doesn't really have a built in way to handle the 'Retina' feature that the Mac does, things would be grainy. You would see the same problem on a Mac App that doesn't use native text or image rendering, that hasn't been updated yet.
So the only way to make it look crisp on your Windows install would be to run at 2880x1800 - which would be hard to see, or a higher resolution than 1440x900 that you felt comfortable with depending on stretching/artifacts/etc. That is until Windows does have some possible feature like this and implemented in a similar way.
When connected to your external display though, Windows is seeing the 1280x720 px, and rendering that correctly, but at whatever your native resolution is. Also, the pixel density on the larger display may be different.
It comes down to the easiest way to understand - the pixel doubling/retina features are an OS feature, not a hardware feature.
