I type everything. Never been the hand writing sort of guy, though I can see the benefits of doing a first draft longhand. I found a program called Scrivener that I do all my work in, absolutely love it. I start out with outlines and then move to the first draft all on the same file. So many great features. (and I hate word too, really hate word).
It does get frustrating trying to think up something "new." But you are never going to come up with something that has never been though up before. Like the story I'm working on now has some similarities to other urban fantasy/fantasy stories, but I've gone off a whole new tangent with a lot of the common themes like magic. Yeah magic has been done over and over again but when you come at with a different angle, it can become something fresh and almost new. So I wouldn't worry too much about your work having parallels with others, unless of course your story is near exactly like another. Hope that rambling mess makes some sense.
And quick question for you: do you outline your work before you start writing? I hate the thought of doing it, but boy is it nice not running into walls in the middle of a novel. Having everything thought out beforehand has been a life saver for me.
