The ability to copy/paste from/to emails, source code, and documents does keep me using task apps instead of paper. Also, I find it very hard to keep large amounts of paper organized in a useful way over longer times, and you need to carry it around. When you keep it online, you can access it from everywhere. Search function is very useful and more efficient than rooting through stacks of old paper. If you have a lot of notes, you'll always lose exactly that sheet of paper that was most important. Good old paper does have some advantages, but it doesn't cut it for me anymore.
