Hey all - sorry about the font problems on Windows. This is just a one page site, and I'm using a font straight from the Google Web Fonts directory. I only have a mac at home, so that was how I tested it. I will certainly be more careful next time, and with a larger site would absolutely test on all browsers and operating systems.
The issue was caused by a webkit font rendering fix. Make sure to remove all text-stroke and text-shadow declarations for windows - these thin out the font and improve rendering in osx, but ruin it for windows (no surprise)
