Font rendering has had some prominence in tech blogs recently, spurred by Apple’s release of Safari for Windows (which very noticably does not use Win32 to render its fonts). Safari on Windows is a wash for me - I can’t see any customer-centric reason for Apple to release it. On the other hand, I am definitely enjoying the discussion because font rendering is a Big Deal for me. I used to be a hardcore Debian user before I switched to OS X. Horrible, horrible font rendering was one of largest factors that drove me away.
Maxim Shemanarev’s contribution to the discussion has been a comparison and analysis of font rendering on Windows, Linux and OS X. It is so thorough that I can’t imagine anyone adding substantially to it. Enjoy!
