I don't. Not during brainstorming. But I always prefer a hard copy of anything over a virtual copy. I think it's sad that newspapers are going under. Accountability goes out the window with all the new technology cyber-action.
It happens a lot. I personally am happier on the keyboard but many of my writing friends and associates insist that writing by hand focuses them, slows them to the right pace, and is essential to their writing process.
computer is much easier than paper since all you have to do is type it right away while paper sort of takes time BUT i prefer to use paper than computer since it gives me more ideas on what to write. Once i start writing on paper and have lots of ideas at the end of it i found out that i've already written quite enough
paper when I'm on the go, computer when I'm home. paper if it's temporary, computer if I need it to keep. paper for others to see, computer for my eyes only. paper for private, computer for virtual exchange.
it all depends on my mood & whatever it is I'm writing.
