If you are suggesting that iOS's keyboard and email client are anywhere near decent, then let me tell you that I completely disagree with you, from somebody that mainly uses his iPhone for emails. Explaining why both "features" smell would take time that I don't have, but there you go: my opinion. In addition, and by challenging fandroid friends, it doesn't seem like Android's email client is any better, at least when it comes to IMAP. Needless to say, gmail works perfectly (duh).
