For a touch typist, it's really quite good. There is a significant difference between this and a traditional keyboard (in that it can be hard to feel where the keys are sometimes), but it's at least as good as the normal MBP keyboards. It can be loud to start with but once you tone down the pressure it's actually quite quiet. I find that I'm still not up to full speed compared with a traditional keyboard, but it's very close. And very pleasant and positive to use.
