I wonder if anyone has experimented with making a laptop that lets you turn off its backlight and use sunlight falling on its lid instead. Doing it without having the entire lid be transparent might be a problem?
I just continue to yearn for something I can work with under sunlight. Still waiting for e-ink to become usable, too. I think the research funding for that has pretty much vanished though.
@anthracite I actually had one for a while. It was a fun little machine, although only useful for the purpose of working on the OLPC project and not as a durable outdoor-friendly netbook like I was hoping for.
But the screen was switchable between backlit and reflective, and that was pretty neat. :)
There are still some military laptops with transflective screens (toughbooks and the like) floating around, but lugging one of those things is A Choice.
