Here is another problem I just unearthed, and it is a relative biggy. I just hooked up my new Powerbook to my 17" Studio Monitor and noticed that the screen was extra bright. So I hit the brightness button to adjust it and guess what? No brightness control! I went into the System Preferences and the Monitor Preferences Pane and there is just no way to adjust the brightness on an external monitor. Congratulations Apple on breaking one of your own peripherals on a new product release! Again! jg
