Im not sure if it only my macbook, but I notice a slight performance drop when I run on the battery v the AC.
I notice that my application load slower, folders open slower and expose and spaces response is also slow as well. is this normal?

Run the software update. Have you?

Do you see this in your Utilities folder?

I also notice a performance decrease when running on battery. I have an aluminum MacBook 2.0Ghz. I just ran Software Update, and no SMC Firmware update came up. I also have no MacBook SMC Firmware Update app in my Utilities folder.
I always thought it was the processor underclocking to conserve battery. It gets really annoying though.
