There is an interesting discussion here at
http://www.postfrontal.com/forum/top...89&whichpage=6
with a lot of pictures I have taken out of new PNAs with 800-900 nits
displays.

This PNA has also a spare RS232. I am searching for a Dell Streak to
compare, but it is was gone out of production a few months ago.
With the sun in front of us, and not in the back, brightness is the only
help to make the screen visible at all.

I am also about to review the Holux 61CS, which is a long awaited unbranded
device with a very good visibility.
(I dont sell them!)
