I'm a Mac guy too, but have also spent years developing sites on Windows. One of the biggest giveaways that tell me a site has been developed exclusively on a Mac and probably not tested much on Windows is the fonts.
From personal experience, stay away from Lucida. One of the most common fonts across all platforms is Arial. I usually recommend using this for your general copy font. The attempt to render Lucida looks really crappy on Windows if its missing, and you can never tell which computers have it and which ones don't. That being said, Lucida is a nice looking font when its available. If you are you looking to use Lucida, read below.
This is a solution that's been promoted for a couple years, font-family: "Lucida Sans Unicode", "Lucida Grande", Verdana, Arial, Helvetica, sans-serif;
Its definitely a good idea to do some cross-platform testing. Another idea is to use the SIFR technique, although it relies on Flash(not my favorite recommendation).
