Actually for drawing Chinese characters it's not that bad. I plan to get an iPad for my parents so they can draw Chinese characters instead of learning how to type (there are many older generations in China who cannot type Chinese on a computer because they don't know how to do that).
I just wish the character recognition could be better.
Oh yes, sorry for the lack of precision, I meant "for western-european languages" (or more precisely for languages with a fairly low number of graphemes), for Chinese or for Japanese Kanji it makes a lot of sense to ask for tracing as providing keyboard systems with good/easy access to thousands of graphemes is not easy.
Though I believe Japanese have a system for such a thing, which they use on regular QWERTY keyboard, my sister demonstrated it to me (you basically type phonetics and it builds graphemes/characters on the fly, something like that). For that reason (and because japanese people are used to that kind of input) iOS has a qwerty (romaji) and a 10key japanese keyboards but I don't think it has a handwritten one (it has 8 different Chinese keyboards, 3 simplified [with "handwriting" and "stroke" versions] and 3 Traditional [Handwriting, pinyin, zhuyin, cangjie and stroke]).
I just wish the character recognition could be better.
