ah, this reminds me of how much JOY I am having using my localized Microsoft Excel. All formulas have been translated to my native language and it's just BLISS to work with. This makes it MUCH easier to search the interweb for my specific formula question. We obviously need much more localization. Particularily in error messages.
I honestly can't tell if you're being sarcastic or not. I can think of ways going for specific formula could be both better and worse. The localised error messages are also a double edged sword - if you can solve your own problem based on the message, they're better, but if you need to Google it your chances of finding a solution go down due to fewer hits.
I get the need for interface localization, but I prefer no translation to a bad one. And many translations are bad.
