ie6vsfirefoxvsfirefoxvssafari
This is the Acid 2 test (www.webstandards.org/files/acid2/test.html ) done on a 13 inch black MacBook running Parallels Beta 3 with coherence running from a boot camp partition. The open browsers are IE6 (left), Firefox for Windows (Top middle), Bonecho for mac (optimized Firefox build for intel, bottom middle), and Safari (Right).
It's interesting that theFirefox renderings on both OSes are exactly the same.
