The quality of my notes (and subsequent work) increased considerably when I started taking notes on a computer rather than on pen and paper. My handwriting was sufficiently unreadable that indices, subscripts, negation signs would all get lost all over the place. Not only that, my mind is less organised on paper than on a computer. Having organised notes would last as long as it took for the first correction or addendum to appear, at which point they'd degenerate into random pieces of text scrawled all over the place, equations inset in boxes in the corner of a page, seemingly random conclusions that were referencing something I'd yet to write. They would inevitably get abandoned later when I came to look over them and couldn't work out what I was talking about. In the end, I gave up writing hand written notes altogether.
The structure provided by LaTeX, on the other hand, I found perfect for formalising notes, and those that I took in this way were usually perfectly coherent and detailed - in fact I believe a set of them is now in use by one of my previous lecturers as his set of notes. After a while, I was even able to replicate graphs and other diagrams (using the PGF/TikZ package) during lectures.
I'm sure it's not the solution for everybody - I'd be very surprised if it were - but neither is pen and paper always the right answer.
