Lots of writers [0] do their first draft with pen and paper. There are studies[1] that show that using pen and paper to take notes boost memory and the ability to recall information, so of course a writer doing the first draft of a long novel would want that for themselves.
I don't understand how one's chosen writing tool has anything to do with technology choices. If one wants to use a pen (as many do find it superior in some aspects to a keyboard) there really is no technological equivalent to a fountain pen. Said he, who loves writing with pen, and owns a surface pro 4, Samsung Note III, and an Ipad, and has found all of them wanting in some aspects.
