What do you classify as a mouse when speaking in terms of notebooks? Are you referring to the nub that say Thinkpads have? If so it all comes down to personal preference but I'd say I'm way more accurate with the nub on my Thinkpad than with the touchpad. I can move to any part of the screen faster with the nub and if for example I'm using the lasso tool in Photosohp I'm way more accurate with the nub. But maybe you're referring to something else?
