You do mention driving, but I'm going to assume you're not operating your phone or laptop while you're actually driving. If this is not a valid assumption, then don't do that. I'm assuming at the very least that if you're in a motor vehicle, when you're operating your device the vehicle is stopped and not in gear. You state, "even the brightest Samsungs, Motorolas, and LGs I've seen cannot hold a candle to the summer sun north of Seattle." One other thing there is a lot of in the area north of Seattle is trees. Put one between you and the sun. Problem solved. If that's not enough, throw a towel over both your head and the device. If it was good enough for Douglas Adams, it's good enough for me. If that's not sufficient, you could bring your device down here and try to use it in the less well vegetated parts of the Mojave Desert, at which point I'm betting that the Seattle sun wouldn't seem so bad.
