pivoting is rotating the screen from landscape to portrait.
I happen to have a PLP setup in front of me, so yes, I'm aware of that. My "turn around" wasn't relating to that.

Anyway...
I don't have a Macbook and it's not difficult to hit a button on the monitor to change brightness. an aluminium enclosure doesn't mean squat since I don't plan on banging it into anything, and I've never banged a display into anything anyway, intentionally or not...it's only there for looks, it's not like the Dell is made of cheap plastic.
That is your preference and others have other preferences. That's why you can't judge a display by such factors. That, and only that, was my point!
Just to reply here, most monitors don't offer the possibility of direct brightness adjustments over a single button. On my Dell 2007FPs I have to go deep into the menu to change the brightness settings. PITA! That's why I use a tiny little tool called
ScreenShade. Highly recommended for third party monitors.
An aluminium enclosure has nothing to do with banging stuff into it. Build quality and appearance come here into mind. Personally (again, ones personal preference), I hate plastic. That was one major reason for me buying the 30" ACD instead of a Dell back in the days. I do mind paying 1500 quid for a display that graunches when touching it. Horrible.
Every Dell display I ever had (and other plastic ones as well) do that, and that's only normal for those displays, no matter how expensive they are. Plastic stays plastic.
Unfortunately, Apple never made 20" 5:4 displays, so I had to buy the plastic Dell ones.

But hey, worse things happen.
BTW: Which 27" would I buy? Dell or Apple?
Definitely Dell! Why? Despite the looks and their plastic enclosure, it comes with a matte panel cover! I hate that glossy stuff. It's just horrible (personal preference, here we go again

).
