Font rendering philosophies of Windows and Mac OS X

Jeff Atword asked What’s Wrong With Apple’s Font Rendering? and as I answered in the comments it comes down to philosophy:

“The primary difference is that Microsoft try to align everything to whole pixels vertically and sub-pixels horizontally.
Apple just scale the font naturally - sometimes it fits into whole pixels other times it doesn’t.
This means Windows looks sharper at the expense of not actually being a very accurate representation of the text. The Mac with it’s design/DTP background is a much more accurate representation and scales more naturally than Windows which consequently jumps around a lot vertically.”
