I agree that the daylight viewing is a definite plus, something that will be essential in the future. The battery savings I'm not so sure about, as it seems users are pretty split on how well the Bionic's stock battery is doing overall. That's not to say the screen isn't helping, it just doesn't seem to be helping enough to sacrifice a higher quality viewing experience.
I got one full cycle on the stock battery, 15 hrs so far and I'm at 15%, moderate use.
