Deliver OLPC / Pixel Qi screens on laptops
The One Laptop Per Child project, whatever you may think of it overall, has one universally-acclaimed feature: the sunlight-readable display. No matter what the lighting conditions, the screen is astonishingly clear -- indoors or in dark light, it looks like a normal screen; in bright light or sunlight, the screen becomes even sharper and is as readable as paper. Everybody I've shown it to says, "Yeah, yeah, sounds great" until they actually try it, and then they go "Wow! I don't believe it!" You won't believe it until you see it.
Go see it. Then get it on Dell laptops.
The lady who developed it is Mary Lou Jeppson; the company she spun off from OLPC to develop the screens is called Pixel Qi. Please go look them up, and do whatever you can to put their screens on your machines. First to market wins a prize -- my bucks.
