I tried 6 years ago but they just won't do it. My airline won't do much either to support Mac. I have found as I guess you as well that Parallels seems to do a fine job. Just stay off email to avoid corrupting your machine.
I'll never understand why the majority enjoys putting up with spam, bugs, and viruses with Windows but I'm glad they do because it is the minority which keeps us free from such contaminates.
