Of course you can be productive on an iPad, no question. I have a keyboard-case for it, so writing a few letters or stuff like that is fairly straightforward and without much hassle. It comes down on what "producing" means for you. I am a developer. Yes, I can code even on my iPhone (code editor, ssh client, git client is installed), but i'm much more productive on an actual mac. If you're kinda office worker that uses mainly office software (word, excel, ...) and messaging (mail, slack, ...), an iPad with optional keyboard is perfectly capable as a primary working device, plus it's extremely portable and may even have mobile data plans attached.
