My MacBook screen is nice and clear, and bright enough that I have never had a moment where I have said "Gosh, this is too dim".
As far as the viewing angles go, I can practically turn my system 90 degrees and I can still see the screen just fine. However, if you are talking about tilting the screen forward or back, then you run into problems quickly.
As compared to a desktop LCD, it is a piece of tin. There is not a single laptop LCD display that can display 8bit color, they all use 6bit panels, so color reproduction is obviously going to be better on a desktop panel, contrast ratio too.
But, the screen works for me, so I am sticking with it.
