Digital BW, The Print

I am using a macbook pro and a viewsonic G810 monitor .
when using photoshop
the viewsonic is my monitor for the "image"
and the macbook pro is for the tools

I'm just wondering if anyone else is using a laptop and a second  
monitor and how they set them up?

I have my macbook in front and below  the viewsonic and things just  
feel a little strange...

before the macbook I used a G4 and two monitors side by side with no  
problem..

any suggestions?
