What are the best laptop monitors for reading in sunlight?

I work with computers, generally writing program code or other text.

I love to work outdoors when it is nice.

It would be lovely to have a nice laptop computer to do this with, but most have a hard time being visible when there is sunlight. My aging Dell laptop’s screen is worse for this than a MacBook I have compared side by side. I hear that the wind-up power charity laptop has a great special screen that is good for outdoors too.

A secondary concern is battery life. The more the better.

Even less important are other computer abilities. I wish people designed laptops for more life and visibility and were willing to sacrifice CPU power, RAM, etc., as those don’t matter nearly so much to me.

So I am fishing for suggestions and tips from the Fluther. Thanks!
