It is actually kind of fun to write out musical notation, taking the music from your head to the page, accounting for note values, time signature, tempo and all that. There is an art to determining note values, especially when you are writing to include blue notes, and syncopation. However, I have not done it in quite some time. I will probably write out arrangements for the instruments when the opportunity presents itself that I can go into a studio with a full band including horns, but all my money goes to college and I have none to speak of for recording right now, so it is not really a priority for me. As far as using software to do it, I have no problem with that, but I love the physicality and art involved in writing on manuscript paper by hand, just as I do writing lyrics. I never write on a computer until I have finished writing it out on a pad of paper. The computer simply provides an easy method for printing it out later that is easy to read.
