I write on my word processor almost exclusively. I do take a lot of hand written notes for my stories and such, but its done quickly and very messy. I do it, though, because I have to get my ideas down quick or my never ceasing brain will just move on and forget what I was writing about.
The way I see hand writing, is that it is a dying breed. The postal service is dying a slow death thanks to email, cell phones, face book, and the like. Without a post office, there will definitely be no more sending letters to people. Who knows if it will completely die, but why hand write when you can text? Personally I loathe and abhor cell phones, but that is a severely minority opinion in the U.S., SEVERELY, minority.
People want speed, convenience, instant gratification, speed, more convenience, and yet more instant gratification. Typing on a key pad or key board is a hundred times faster than hand writing. I don't think its possible to write faster than a good or even average typist can type. I use only two fingers to type and I can go freaking fast when on a roll; I make quite the racket as I hammer my keyboard. Imagine a person who is really good with ten fingers.
With the internet and its ability to store data, its becoming highly attractive for storing information digitally instead of physically. So the loss of hand writing isn't just for convenience, its for a practical reason (although not by much, since information theft and loss is so rampant over the internet).
Unfortunately like good English (grammar, etc), hand writing is a thing of the past. Only "old fashioned" people, like me, really even care anymore (I'm only 26, but the English language fascinates me, as an aspiring author). I know that's a broad sweep, but I believe it to be true. I think its well known, unless more people do it than I think.
