There's nothing "lame" about using a computer to write lyrics, they're easier to revise that way; as well as being easier to read. I was going to use the computer the other night, but as Potter said - the pen helps get me in the mood to write, it makes it more personal. If I'm not writing the words, I can't come up with the words. So I rarely use anything other than pen/paper for my writing. Unless it's something like a rushed poem or something.
Peace
