I love Expose, but so far haven't trained myself to use it consistently. I'm too wild with the cursor to enable Expose using hot corners, so I'm using the F9-F11 default. Those keys are a little hard for me to hit on-the-fly on my Pismo.

Using this tip gives you a translucent button on the screen which you can click to use Expose...

I'm hoping by seeing it it'll make me think about it more. Then I'll use Expose more. Since I prefer the keyboard, I figure it'll also get me into the habit of mastering the keyboard shortcuts as well. :-)
