I haven't heart anything so stupid in a long time. I's always worth to translate into major languages apart from English unless your application is about English-specific language jokes
I've got iPhone 4, my wife 4S. I spend a hundred or so $ on apps every year. My wife not a dime. Why? I want to show her a great/useful app, but she says: "In English only? No, thanks."
She DOESN'T CARE to write to developer to translate their apps. She just ignores them having been ignored by them earlier (by their not providing localized versions).
So your wife isn't willing to learn English and yet judges someone who equally chooses not to learn her language? What makes her so special?
