I remember a while ago Apple did some browser sniffing on mac.com and simply refused connections if they couldn't identify the browser/OS-combination.

I don't know what those people are up to and why they can't use standard HTML and some scripts as everybody else on the web does. - Although they seem to have given up on this practice (or maybe just know my browser/OS now, who knows?), I very much doubt that any problem with Apple's sites is browser related.
