I recommend the type cover as well. I've been able to get 80-90wpm on it where as with an apple keypad I can get 100-120wpm, so its not horrible. The response is pretty good, the trackpad is atrocious, then again, I'm coming from Apple's trackpad. The type cover trackpad reminds me a bit of a netbook's trackpad, but hey, at least its functional.
I would definitely not recommend the touch cover as there's a very noticeable typing lag.
