My 12" powerbook runs Virtual PC with Windows XP Home and Internet Explorer 6, 5.5, and 5 for testing. (I can even print from inside Windows XP to the same printers available to the mac OS.)
Firefox works basically the same across platforms, so test sites with that.
Standard, valid code works better across browsers, so validate your code, for example at [validator.w3.org ]
Minimize use of JavaScript. Especially eschew non-standard JavaScript functions.
