I agree. I tend to type everything I can, it's just faster. However, math and physics, or anything math related is easier on paper, especially when it comes to exponents and subscripts. It's faster to write those than format the page. But then math is one of those things that should be done by hand mostly anyways. And for math and things math related, pencil is the way to go. It's easier to erase mistakes than cross them out for math. Other stuff I don't mind pen or pencil too much, like essay tests in english for example.
I type faster than I write, and I can write fairly quickly.
I agree though, sometimes, I do tend to remember more stuff when I write it. But it doesn't matter too much, as long as I am concentrating on what I am typing.
