Earlier quoted context omitted.
Not to mention the URL… http://www.microsoft.com/en-us/default.aspx , really? Have they not heard of internal/external URL mapping and Accept-Language? Not to mention it won't even load for me; I guess they don't cache this stuff either.
What is wrong with that url (except default.aspx)? It's widely used and I like if I'm not forced to some region or locale based on my IP and Accept-Language. Well, I still am but I can change it easily if they give me this url (or even better link on a page).
Accept-Language is trivial to change; on Opera, it's one of the three things on the first tab of Preferences, and I can set it for all sites rather than on a per-site basis.
