I use Emacs' org-mode for pretty much all my work notes. It's very structured, long and includes spreadsheets.

But usually I don't use my laptop during work. Instead I print just day's notes (schedule etc.) to a single paper sheet and keep the note paper with me. I do corrections and maybe add notes with a pen. Then later at home I modify my org-mode files to match my note paper.
