You may find that quite a large percentage of US and UK market reads/write/speak asian languages. (Especially Chinese wouldn't you agree?) I really don't think adding some extra asian language support (just for reading/writing) isn't that hard. It's not like they've never done it before. If they do it, they'll sell even more. Why block out certain potential customer base due to not investing an extra few days? (maybe it takes less than a day? never know) Doesn't make sense.

Well, I hope it's as easy as just copying another font on to it.
But I would love CJK IME support for sms,email,browsing etc.
