Don't take "good enough" if you are paying for "better".
It really is a bad screen for the money. Really bad.
It is a relative statement, for the money it should be better than my 3 year old cheap Evesham (have you even heard of them?), and it isn't.
It is EASILY useable in everyday situations, but I'm paying £1150 which is not everyday money, so it better kick arse in all situations.
Saying stuff like "how often do you even look at a black screen!??!" is just chumpish crap that makes people like Steve Jobs wet their pants with excitment whilst you pay top whack for a screen he probably got for half the price that Dell would pay to put a decent one in.
I boot up Vista and it looks like brain-matter grey all across the bottom and black at the top. Once you have seen this you will notice the dock is washed out.
I watch movies all the time on laptops, and there is usually a black bar top and bottom. Well, I say a black bar top and bottom, I mean a grey bar at the bottom and a black one at the top.
