I'll grant you outside, because the power of the sun is immense, but they're definitely bright enough to use in any well-lit indoor environment. Do you mean if the lights are behind your head instead of overhead? That's either bad lighting or bad ergonomics, and I'm sorry if you must suffer through that. That sucks.

An ergonomic screen arrangement, with the display perpendicular to the desk and height-aligned with your horizontal line of sight should make it basically impossible for an overhead indoor light to interfere with your view.

Fingers crossed. I remember yearning for the breakout of transflective displays that never happened.
