Ignoring the browser language pref (Accept-Language) to
get you to make an account - this annoyance has been there since they started offering different language versions.
It also ignores the fact that I'm signed in to my account. There's a separate preference cookie that remembers the language, but it has to be set for each country-specific domain. There's http://google.com/ncr but that doesn't solve the problem across all google services. Buying things is especially problematic.
