This "Browser racism" is nothing new. Its existed for years, back when netscape 4 was king. Sites were either designed for MS IE, or netscape, or even sometimes both, leaving out browsers from alternate platforms such as linux, unix, and mac (or even BeOS). I have downloaded windows vista beta 2 from MS with all three browsers, opera, firefox and IE, no problems at all. I am using opera 9 beta 2, firefox 1.5.0.4, and ie 6 sp2.
