Other than messing with the luminance and contrast how else can they change the behaviour of a display. And if it is all implemented in software why doesn't it work on any screen.

Stinks of fish to me.

I guess this solves the problem for the neighbouring seat guy wants to see a little more of Paris.

Mmm, yet another triumph of marketing hype over truth.

Difficult to understand how Dell, with their recently announced R&D cuts, down from an already miserable 0.8% (vs HP's 3.5% and Toshiba's 6%) managed such innovation.

The truth is, they didn't. I remember a Tosh Tecra M3 having such a device 3 yrs ago. That notebook has been superseded, I guess, so not sure of current status, but think Dell's claim of being first to market should require a huge suspension of disbelief to make that one palatable!
