There are some other characteristics as well. With pen and paper, you can only move forward. That is, your only real option is to complete the draft. You can revise or rewrite when you're typing it in. Neil Gaiman writes this way; fountain pen and notebook for first draft. Cutting material is much less painful. You simply don't type it in.

The temptation to go back and tweak what you've written is fairly strong with modern tools. An author can waste hours, an entire writing session, on rereading what they wrote and making adjustments. That's an activity best left to after you have a completed draft in hand.
