On the other hand a mouse is more efficient for pointing at things than anything else I tried - touching the screen, touchpad, etc... it's why when I'm working on my laptop, even though being on a MacBook I have a pretty good touchpad, I'm still attaching a mouse.
Same goes for the keyboard - no matter how big the screen real-estate is, it doesn't beat a physical keyboard, because a physical keyboard gives a tactile feel to your fingers and thus you can do touch-typing. My wife doesn't do touch-typing, she's just an ordinary user, but even she complains that things are hard to type on her 11 inch iPad.
Indeed there are applications that are more productive with a touchscreen, coupled with the possibility of carrying them around and looking at the screen while walking, it's a good combination - but for very different things.
