We currently render math images only for traditional screen resolution; on high-density screens (eg iPhone 4) and when printing, these can look blurry or blocky.
Rendering another PNG at 2.0x the size would be suitable for iPhone & iPod Touch Retina display, Samsung Nexus Galaxy, and printing.
1.5x would be suitable for many phones running at an intermediate 240dpi-ish resolution (Droid, Nexus 1, all Windows Phone 7 phones, etc).

Dropping this idea in favor of MathJax, which produces fully client-scalable HTML or MathML (bug 31406).
Reopening this; MathJax has some issues with printing and compatibility, so we might end up going with the higher-res rasters for default behavior.
Brion, could you provide more information about these issues on the MathJax bug tracker? https://github.com/mathjax/mathjax/issues
