I use several of the methods mentioned. I am currently in rehearsals and recorded all of my scene partners' lines to my computer, leaving the aformentioned space for my own. I then transferred the files to my iPod. I can run lines any time, anywhere.
For monologues, I find it helpful to write them out longhand. For really long monologues (i.e. Laughing Wild or Paul's in A Chorus Line), I also type them on the computer.
Interesting point Dolly. I had never thought of that, but it makes sense.
"I am open, and I am willing,
For to be hopeless would seem so strange.
It dishonors those who go before us,
So lift me up to the light of change."
