I definitely think that the worst part about typing on a computer is how easy it makes it to not draft. I write about music on the side, and if I spend 15 minutes planning what I'm going to write prior to actually writing it (for a 500 word piece) then everything turns out much more cohesive at the end. I can pretty much type as fast as I can think, but my thoughts are pretty garbage unless I get a chance to organize them first.
