I decided to switch over to the Dvorak keyboard layout last night.
I switched simply because I wanted to try something different and thus far I must say that I like Dvorak.
To become fluent with the layout I am currently using the dvorak7min typing tutor.
When I am not using the tutor, I have a small image of the layout sitting on the bottom of my screen. Needless to say, both of these have proved to be very helpful..
I'll probably post an update on my status within the next two weeks.
