You can run your Powerbook screen and the ACD at the same time. You have three options when running an external from your powerbook. You can:
A: Close the lid of the powerbook and operate in "clamshell" mode. In this mode, you only have 1 screen, but 100% of your GPU is dedicated to the external monitor.
B: You can have the lid of the powerbook open and the screen showing in a mirrored fashion. Whatever happens on one screen, you see on the other. This is especially helpful for presentations, etc...
C: You can have the lid of the powerbook open and the screen showing in a dual-monitor fashion. This will give you more screen real estate, but your GPU's power is divided in half (which is fine since you have 128mb of RAM).
I'd recommend getting the 23" for your Poker stuff and then just using the internet and misc apps on your powerbooks screen. Combined with an iCurve or similar stand, external Keyboard and Mouse, this makes a great setup.
