Working in the sun requires a computer screen that can handle the light

I been searching the internet quite a few times for information about what laptop displays are viewable in direct sunlight. I have to today a PC Tablet from Fujitsu Siemens that does the job well. Its a p1610 8,9" and it handles direct sunlight well except from the reflections as the screen is glossy. I'm not sure if this is for all tablet pc's but I think it is a better chanche that they do have a screen that works well in direct sunlight.
