Font smoothing, anti-aliasing, and sub-pixel rendering - Joel on Software - http://www.joelonsoftware.com/items...
I use OS X and Windows regularly, but I still find the OS X font rendering rather blurry. I can certainly appreciate the same-as-the-printed-page fidelity of OS X (I was the production manger at a student newspaper long ago). However, these days I view most content on-screen and so I would rather the displayed fonts be optimized for on-screen than on-page viewing. - Simon

For the standard Windows fonts (well hinted), the Windows rendering is nice, and the OS X rendering is blurry. However for most fonts (*), the Windows rendering is horrendous, and the OS X rendering is blurry but good. (*) I've been looking at lots of fonts from Google Font Directory, TypeKit, Font Squirrel, etc. for possible use on my web pages, but they all look so awful in Windows that I'm only using the default fonts for now. :( - Amit Patel
