Personal devices spark war over planes' windows

• Many daytime flights have begun to travel in the dark, with some Boeing 787 flights disabling individual controls to keep windows dimmed throughout — and flights from Asia to North America often block passenger control entirely.

The other side: Many want the shades kept open to enjoy the view, gain reading light or keep one's internal clock in check.

• Some customers who favor light complain that pressure from seat mates or controlled windows make them feel cheated from their window-seat experience.
• Delta says it's even had to address customer conflicts over window light, which they resolve by relocating passengers into areas of the plane favoring dark or light.

The bottom line: Window seats were once coveted for their view. Now, they're a matter of power, thanks to technology's ever-growing influence on our lives.
