I find my Pa1XPro screen is at too shallow an angle, and it would be nice to have angle adjustment as on the 2X.

As Donny mentioned earlier, you never know what lighting conditions you might run into on gigs and too often I've had fluorescent lights overhead in just the right/wrong position. Yes, you can move your rig a few inches either way sometimes, but that's a PITA. An adjustable tilt would solve the problem for sure.
