No. I use it all the time. Pencils, too. I write books in pen, articles on the keyboard. I like the pen because it forces me to slow down and I can turn back the pages rather, see things at a glance, rather than scrolling back to find what I want. I find it just easier on the eyes and brain as well. Sometimes its just good to get away from the computer backlight..
I feel my writing is better when I write with a pen, not legible but it tends to flow better. That said, I use the keyboard more these days. I mainly use pens to write short notes and ideas when not at my computer.
Sure, typing is easier and faster, but I've got a feeling we'll all be missing those hard copies of personal letters, letters, and memos and factual information as opposed to that gets misplaced or lost in cyberspace.
