This blogger (http://scobleizer.com/2006/08/17/linux-achilles-heel-fonts/) says that what keeps him from using Linux is "readability, fonts, and aesthetics." That is, he won't use Linux because the fonts are so bad. He goes on to say that Microsoft and Apple are winning the operating system wars because type designers (he specifically mentions Matthew Carter) don't work for free.
Then, a columnist at ZDNet picked up on this topic (http://blogs.zdnet.com/hardware/?p=70). He says that Windows fonts are better than Mac fonts are better than Linux fonts are better than personal electronics fonts (cell phones, MP3 players, etc.), and that Linux could pick up users by improving its fonts. He says readability and quality fonts are important to users who spend a lot of time on their computers, and that "bigger, clearer icons and better fonts" are reason enough for him to upgrade to Windows Vista (I assume he means the Aero user interface).
So it looks like computer geeks sometimes notice fonts and think about readability (whatever that means to them), but does anybody here think fonts do or could influence the general user population in their choice of OS, or make them switch from one OS to another?
