Just got my new 17" Powerbook. Now, we've all heard the great points - Brighter screen, faster hard drive, great resolution, etc etc.
Issue #1:
Poor vertical viewing angles. If you tip the display back and forth, the brightness shifts noticeably.
Here, I made a gif of the brightness shift while being tilted for visual aid. White is the brightest part of the screen.

Issue #2:
The very lower left and right corners of the display are dim in comparison to the rest of the display. Also seen in the above gif.
Issue #3:
The screen release button on the front of the powerbook is very very difficult to press in.

That's all for now.
Everything else is great!
