I just got a rMBP yesterday. It's surprising/disappointing to me how gross non-retina apps and websites look. Almost worth switching back.. almost. Retina apps are so buttery smooth. I really hope there is wider adoption over the next couple of months.

I actually submitted a bug to the chrome team about this. Both Apple and Google have screwed up their scaling algorithm, they're using bicubic scaling instead of nearest neighbor scaling and it make everything as you say look "gross"

You can see the issue here http://craftymind.com/factory/retinascaling/retina.html

Why is nearest neighbor scaling better? It would make images look like on a non-retina display, but is that the best use of the additional pixels? Nearest neighbor scaling is usually considered one of the worse scaling algorithms, unless you're looking at pixel art.

Why go to the trouble of exactly doubling linear pixel density if you aren't even going to use nearest neighbor?

I just got one last night. I am overall very impressed, although I agree that it really is jarring to hit an app that's not designed for Retina.

Have you tried running the native resolution? It gives you tons of real estate and avoids the retina compatibility problem, assuming your vision is good enough :)

You can't get the native resolution from system preferences, but there are some utilities that make it pretty convenient to get at it: http://osxdaily.com/2012/06/18/3-ways-to-run-a-retina-macboo...

I recommend SetResX on that page, it's free and works really well, and just sits in your menu bar. Just watch out on the downloads page, there are a bunch of ads that look like the download link, make sure you get the right one.

I just tried it- everything is comically small :) Do you run at 2880x1800?

I've settled on 1680x1050 for browsing and jump up to 1920x1200 for coding.

I can use it at 2880x1800 when I'm sitting down at a table and can sit still close to it, but it's too small for casual use. I've mostly been using 1920x1200. It is impressive though!

I wouldn't be too concerned on the app front. The situation was the same when the iPhone first got its retina display but these days most apps are optimised for it.

The web side of things is a different story. AFAIK, there isn't even a nice way to send hires images to hires displays without adversely affecting those browsing with standard DPIs.

I believe apple came up with a tricky way of doing this on their homepage.

Gross compared to retina-enabled apps or gross compared to a non-retina MBP?

Think standard definition television programming on a modern HDTV. It's pretty much like that.

Gross compared to a non-retina MBP. The anti-aliasing tricks that many apps use for their text rendering are broken in HiDPI mode. Use SwitchResX to change the resolution from 1440 x 900 HiDPI to regular 1440 x 900 mode and there is a noticeable improvement. I'm often forced to switch (to 1680 x 1050 so it's like the old high res MBP) because shockingly Apple's iWork and iBook Author aren't updated for the retina display.
