I've found the Cornell system a good way to start including mind mapping you don't have to write only notes in the wide column you can do mini mind maps.
I like the Cornell system as a transistion to mind mapping. The PhotoReading system changed a lot about our approach to learning. Many people already have methods that work for them that includes taking linear notes. While good the complaint is they still take a long time to write, hard to keep up in lectures and take longer to reveiw because you have to read that lovely hand writing. Which often deteriorates to looking like chicken track on a barb wire fence. But when it works it's daft to drop that in favour of a new toy like mind mapping. Like learning to take notes like that it's going to take a bit of practice to explore mind mapping.
The good thing about Cornell System, there is space on the paper where you can do mini mind maps keep using a linear note making system.
Ultimately once you start including mind maps you might find the Cornell system too slow and eventually drop it. Or reverse it. Do a mind map with a list of data down the side.
Cornell notes isn't the only other workable note making system. There are others that are even better suited to some subjects.
While in the long run I've learned to appreciate mind mapping. The only other kind of notes I make are postit notes 
I'm all for sticking with what you know. Rethinking our approach to reading is a big step changing. How we make notes is another one. We normally adjust the training wheels on the bike before we take them away. And we ride the bikes with a frim grip for a while before we start crying out look Ma, no hands.
Christoph, didn't you get a copy of my notemaking article?
