So I picked up a 23" from my Apple store this weekend, I LOVE IT... but I do have a couple questions. On the display at the apple store when I used the buttons on the side to control brightness the little brightness meter came up on the screen (similar to how it does with a Powerbook). However, it doesn't do this for me on my G5. Also on the setup at the Apple store you could change what you wanted the power button on the display to do, either put your computer to sleep, turn off the display, etc. Now all that button does is turn off the display. Any new 23" or 20" owners have some advice?
