It works really well with one exception - a friend has an iPad which is 1024px wide but it's a retina display with a 2x pixel density (thus acts like a 2048px width) - but my site is switching to small-screen mode because of the @media command being based on screen width.
The trick with retina displays is that browsers use it differently than you think it should be used.
A retina screen is used by a browser to increase the quality of the thing being displayed, not to make the screen "bigger"
So if you have an iPad that has a width of 2048 PHYSICAL pixels, a browser will use ALL measurements you give it to make the entire screen have 1024 LOGICAL pixels.
What it does however is draw things like fonts much crisper. It can also if you let it scale images draw much shaper images as well.
