Microsoft vs. Apple on Anti-Aliasing

I was wondering why the font rendering on Safari for Windows looks so different. Actually I've used a Mac for the last 4 years, but seeing Apple's anti-aliasing rendering engine working on Windows does feel a little bit strange. Joel Spolsky outlined the differences between two camps:

  • Apple generally believes that the goal of the algorithm should be to preserve the design of the typeface as much as possible, even at the cost of a little bit of blurriness.
  • Microsoft generally believes that the shape of each letter should be hammered into pixel boundaries to prevent blur and improve readability, even at the cost of not being true to the typeface.

Well, as I am reading large amount of text every single day on computers, Microsoft's Clear Type seems to be easier on my eyes.
