This poll started in Dec. 29, 2005? I didn't get to vote! 😱
If I had, my vote would have gone to fountain pens.
Rollerballs? To me? Sorry, no way...
I'm a fountain pen man.
Parker's my favorite brand. Waterman comes second (I only have one, alas) and then Sheaffer (two, one surviving from my high school days). My usual tools are one of my three Parker 45 (one black, one blue, one in brushed steel), or my Parker Sonnet, my Parker 75 and then my Sheaffer Prelude in gold (writes gloriously! 😉 ).
My one and only Waterman was so pleasant to use, I simply forgot the other pens. Then I put it back in my wooden fountain pen box for too long. It's back on the saddle again! I use it, just as my other pens, to doodle things, to write outlines that later will become articles or other things, and to grade students' papers and record grades in my gradebook.
These were my pens when a gift came from a fellow RFF member: he sent me a Cross and two Sheaffer Targas he no longer used. The Cross... is a pleasant, sleek pen! About the Targas... no luck finding a converter or at least cartridges (and the Sheaffer stuff I have just won't fit them). But they're clean, in case I find something... some day.
My coolest looking pen was a Parker Falcon. It was stolen, so I bought another... and got stolen again. However, thanks to evil-Bay, I found one and has also come out with me. It's brown, it's gorgeous, and it's also discontinued... 🙁
I use them most of the time (after losing one of my 45s, I made a principle of not taking them out unless my shirt has a pocket... although I can always put one in my bag). I also wash them in cold water every time I change ink colors (my wife gave me a set of ink bottles that looks like a rainbow).
Heck... did I say I'm enjoying life?
